Abstract: |
Hydraulic fracture is a useful technique to apply for remediation of contamination in soil and grouting during tunneling work. The effectiveness of the technique highly depend the fracture orientation and geometry. The used of hydro-fracture grouting during the tunneling is popular in construction industry. Moreover, hydraulic fracture technique is also an enhancement technology to increase formation permeability for the extraction of organic compounds from soil. In fact, the general criteria for predicting the hydraulic fracture still have not been established. The prediction of fracture orientation still heavily depends on crude empirical relationships, which are in general unable to match for complex situations in the field. The generation of excess pore water pressure during the hydraulic fracture has not been investigated. Furthermore, if the hydraulic fracture is not operating in a good controllable condition, it may cause the influence on the underground structure and superstructure, undesirable ground heave outside the target treatment zone. The proposed research aims at establishing the criteria for predicting the hydraulic fracture orientation and developing an effective fracture controlled injection technology by performing a series of laboratory tests. The main purpose of the project described herein is to develop a high efficiency fracture-controlled theory and to recommend new criteria for design and operation in different techniques. o to seek a method for predicting the soil fracture direction of single and multiple injections o to investigate the grouting behavior, the influence the hydraulic fracture on the soil properties (permeability, soil density and shear strength) |

Abstract: |
The increased anthropogenic effects on the natural surroundings (Lean and Warrilow 1989) require a physical-based numerical model system urgently for understanding and predicting potential consequences caused by such effects. Meanwhile, the improved capability in modelling land-surface hydrologic processes (Sellers et al 1997) makes it possible to use a physical-based system to evaluate the availability of the water resources and to study the sustainability of the environment. However, the limitation of our understanding in the hydrologic cycle still is the major obstacle to advancing the model representation and to applying the model prediction, which can guide our regulations in mitigating the natural hazards. For relaxing this limitation, the objectives of the project are planned as follows: 1. To identify the sensitivity of different land surface processes in a coupled land-atmosphere numerical model system, 2. To integrate achievable new understandings of hydrological processes into the land surface parameterization in the coupled model system, and 3. To evaluate the improvement of land surface performance in the system (see Reference at the end of Section VII) |

Results of this landslide research can help to determine whether an old landslide is identified as being reactivated by the influence of the fluctuation of reservoir level, and whether it will be fast moving. |

Abstract: |
- Objectives: (1) To characterize the types and concentration of the disinfection by-product (DBP) precursor material in wastewater effluents of various degrees of treatment and the resulting DBP types and abundance in finished drinking water; (2) To investigate the stability, transformation and the change in the DBP formation characteristic of the wastewater DBP precursors in the surface water environment undergoing biodegradation and sedimentation. - Key issues and problems: Due to the worldwide decline of water resources, treated wastewater has become a growing portion of water supplies. Many surface water bodies, i.e. rivers, lakes and reservoirs, are used for both wastewater disposal and fresh water withdrawal for drinking water. The percentage of treated wastewater in drinking water sources could be as high as 100% in some cases during the drought season. However, little is known about the impact of wastewater discharge into the water resources on the DBP formation in finished drinking water. The wastewater-derived DBP problem can be much more serious in developing countries due to the lack of wastewater treatment and water environment protection. For example, along with the rapid economic development in China in the past two decades, more than 80% surface water resources are polluted to various extents by sewage disposal, including the East River in Guangdong that provides more than 70% fresh water supply of Hong Kong. Deterioration in the source water quality greatly impairs the capability of conventional water treatment, especially for DBP control and minimization. Natural organic matter (NOM) in surface water has been considered as the predominant DBP precursor (Singer 1999; Xie 2004). Numerous studies have been conducted on the characteristics, reactivity and DBP yield of NOM in chlorinated drinking water. However, there is little information about the DBP precursors brought about by wastewater discharge. Organic impurities that are present at higher concentrations in wastewater effluent than in natural waters would make a considerable contribution to DBP formation in drinking water (Galapate et al. 1997; Rostad et al. 2000; Chu et al. 2002). Wastewater precursors with chemical features different from NOM may lead to the formation of different DBPs than those typically formed in drinking water systems. On the other hand, natural reactions and processes, such as biodegradation and sedimentation, would affect the stability and transformation of the wastewater DBP precursors in the receiving water, altering their reactivity with chlorine in DBP formation. These wastewater-derived drinking water DBP issues remain to be addressed through experimental investigations. . |

Abstract: |
The finite element method is now a well established tool for the analysis of complicated engineering structures of irregular geometry, such as tall buildings, bridges, automobiles and aircraft, etc. However, this versatile technique gives only an approximation solution whose accuracy depends on the number of elements and the sophistication of individual elements used in the finite element model. With the introduction of the adaptive refinement procedure, the goal of achieving economically reliable finite element solution of specified accuracy for general three-dimensional problems is possible and feasible. Many high-performance solid elements of various geometrical shapes and orders have recently been developed based on the hybrid stress approach and the weak continuity requirement between elements. Parallel to this development are advances in the automatic mesh generation techniques over curved surfaces and within three-dimensional volumes [1-5]. A research project is proposed to bring the latest advances in solid element technology and the mesh generation techniques together to form an integrated adaptive refinement analysis scheme for providing high-quality economical solutions to practical engineering and benchmark problems, which cannot be obtained otherwise by classical simplified models of reduced dimensions. |

Abstract: |
The aim of this study is to establish a reliable and practical model for evaluating the concession items put forth by the consortia in a Public-Private Partnerships (PPP) scheme so as to attain a "win-win-win" situation amongst the public bodies, private organisations, and end-users. The objectives of this study include:i) identifying the Critical Success Factors (CSF) for PPP projects and their impacts on concession evaluation;ii) examining the current practice being used for evaluating the concession items; iii) devising a fuzzy evaluation model to establish the impacts brought by concession items initiated by bidders; andiv) validating the fuzzy concession evaluation models using synthesized and real data. There is a growing awareness of the benefits seeking private organizations' involvement in providing and operating public facilities and services. Public Private Partnerships (PPPs) constitute an emerging approach that utilizes the financial, technical, managerial and commercial strengths of private enterprises to deliver public facilities/services which would otherwise be difficult to provide (Akintola et al, 2003). Through PPP, private partners would have a greater incentive to identify and adopt innovative approaches in providing and/or operating the facilities, and this could result in cost saving and an improvement in service quality (Smith, 1999; Chege and Rwelamila, 2001). With a shortage in public funding, there is a growing pressure for the public agents in Hong Kong to adopt the PPP concept (cf: Angeles and Walker, 2000), and examples of these including the much debated West Kowloon Cultural District, High Speed Road Maintenance Project, etc. While there are established mechanisms to measure the performance of private partners and regulate the tariff/charge during the operation stage, they are usually protected by an assured revenue stream (especially those working under the concession-based PPP) meaning that they can raise the tariff/charge should their revenues fall below the desired level of return (Merna and Smith, 1996). As a consequence, awarding a PPP project to one who proposes a very low tariff might sound attractive at start, but may eventually result in public discontentment and political upheaval should there be an incessant increase in tariff/charge like what is happening with the Western Harbour Crossing in Hong Kong. A major review on the literature and the technical circulars of the HKSAR Government reveal that there is a lack of informed approaches in evaluating PPP concessions. There is a need to establish a reliable yet practical strategy for evaluating concession items, viz. the (i) ideal concession or operating period; (ii) relationship between the tariff/charge and expected return; and (iii) stability of tariff/charge. However, to evaluate a PPP concession is never an easy task as decision-makers have to rely on a number of vague assumptions and the results may also be affected by the risks and uncertainties during the development and operation stages. Potential risk factors affecting the revenue include (i) cost overrun triggered by inflation, technical or managerial shortfalls, climate or environment change, and other such factors; or underestimation of revenue due to shrinkage in demand, recession, increased competition, etc, which are difficult if not impossible to quantify at the concession evaluation stage. When evaluating the concession items, risks and uncertainties must be duly considered. In this study, a concession evaluation model will be developed based on the fuzzy sets approach to improve the reliability and efficiency of this kind of decisions. |

Abstract: |
A large number of civil infrastructures and buildings around the world are in a state of serious deterioration due to weathering and aging. Moreover, many structures are no longer considered safe due to increased-load specifications in the design codes. In Japan, the vehicle load designed for highway bridges has recently been increased by 25%. Similar situation has occurred in European Union countries, as currently all the major roads and associated structures are required to be upgraded to carry up to 40 tons total axle load which may overload many existing bridges that were built over the last 40 years. In Hong Kong, new seismic code is expected to in forced in year 2010, new loading provisions would be imposed to existing buildings. These new load requirements have put the safety and integrity of many existing structures in question. Reinforced concrete (RC) material is not good in recycling, to reuse the structures and to protect the environment, substantial strengthening, retrofitting, refurbishment or rehabilitation of different structural components are required. Strengthening of existing concrete structures by using bolted external steel plate has recently been attracted much attention [1-4]. The behaviours of the bolt groups that play a key role in the strengthening works need to be thoughtfully studied. In this proposal, the full range of linear and non-linear responses of bolt groups is to be determined by experimental study and numerical simulation. New theory based on varying the position of the point of rotation of the bolt group and hence the bolt forces to balance the applied loads is proposed. New computer program would be developed to verify the theory. Experiments would be conducted to measure the non-linear load-slip relationship of single bolts. Owing to the versatility of the proposed theory, it could cater for different stiffness, load-slip relationships of bolts as well as various loading conditions. The theory is expected to widely use in many different strengthening works.

Abstract: |
It is now well recognized that road safety is a public health problem. Road safety was the theme of World Health Day 2004, on which hundreds of organizations around the globe hosted events to help raise awareness about road traffic injuries, their grave consequences, and enormous costs to society. This addresses the fact that road traffic accidents are among the eight leading causes of death worldwide. Each year, around one million people die in traffic accidents. In Hong Kong, a major traffic incident involving a container truck and a double-decked bus occurred on 10 July 2003 on Tuen Mun Road, resulting 21 fatalities and 20 injuries. In response to this incident, the Chief Executive appointed an Independent Expert Panel, of which the investigator was one of the three members, to examine and make recommendations on road safety measures for improving road safety. This has led to a publication of the “Report on Enhancement of Highway Safety”, in which a number of road safety measures were proposed. Many of these measures are currently being seriously considered, and will be put on trial or implemented soon. In addition to these measures that are mainly for high speed highways, other road safety measures in urban environment have also been implemented in the past few years or will be implemented in the distant future. It is essential to develop a methodology that can help evaluate the effectiveness of these road safety measures in reducing road traffic accidents and casualties. This project aims to develop an observational before-and-after study methodology to evaluate the safety performance of road safety measures, and use the road safety schemes that will be implemented in Hong Kong as case studies to demonstrate the usefulness of this methodology and more importantly the effectiveness of these schemes in reducing traffic accidents and casualties. |

Start Date: |
06/2005 |
Abstract: |
Cold-formed steel structural members may
lead to more economic design than hot-rolled steel members as a result of
their superior strength to weight ratio and ease of construction. Cold-formed
steel beams are used increasingly in light gauge construction. The use of
high strength material could improve the load carrying capacity of the
structural members. Therefore, cold-formed steel beams fabricated from high
strength material would lead to cost saving. The existing "Hong Kong
Code of Practice for the Structural Use of Steel (Limit State Approach)"
is limited to steel grade of 450 MPa. The Hong Kong Steel Code does not cover
high strength material of yield stress greater than 450 MPa. Furthermore,
high strength material is not as ductile as normal strength material. Hence,
there is a need to investigate high strength steel material. Web crippling is
a form of localized buckling that occurs at points of concentrated loads or
supports of structural beams. Cold-formed steel beams that are unstiffened
against this type of loading could cause structural failure by web crippling.
Transverse stiffeners can be used to prevent the structural failure. However,
transverse stiffeners are often difficult and uneconomical to install on
structural steel beams. The purpose of this research is to investigate the
behaviour of cold-formed high strength steel beams. A series of tests will be
carried out on cold-formed high strength steel beams subjected to web
crippling. A non-linear finite element model will be developed based on the
test results. The experimental and theoretical investigation would provide a
better understanding of the behaviour of cold-formed high strength steel
beams subjected to web crippling. Hence, design rules for cold-formed high
strength steel beams will be proposed. These design rules can be used locally

Abstract: |
The use of cold-formed steel structural
members has increased rapidly in recent years, especially in cold-formed
steel construction, such as steel-framed housing, office buildings, factories
and warehouses. Cold-formed steel can be used efficiently in many
applications where conventional hot-rolled steel members prove to be
uneconomic. However, traditional cold-formed steel sections, such as channel,
Zee and angle sections have been well investigated. Therefore, a new type of
innovative cold-formed steel sections are needed, where the new sections will
be structurally more efficient and econmical than the traditional cold-formed
steel sections.The purpose of this research is to develop a new type of
innovative cold-formed steel sections through both experimental and
theoretical investigations. New design rules for the innovative cold-formed
steel sections will be proposed. The new innovative cold-formed steel
sections can be used in |

Abstract: |
To investigate the microbial community in the activated sludge treating Hong Kong's saline sewage. Hong Kong is leading the world in treating saline sewage, which results from the fresh water conservation by large scale seawater toilet flushing. Several secondary municipal sewage treatment plants in Hong Kong successfully treat a total of about 200,000 m3 saline sewage (containing 6000 mg-Cl-/l as the average) daily to produce effluents in compliance with the discharge standards. It is thus of great scientific and engineering importance to understand the diversity and characteristics of the halophilic (salt tolerant) microorganisms in such activated sludge, and yet very little related information is available. Results of this study shall provide valuable information that will be needed to further improve the effluent quality of Hong Kong's sewage treatment facilities. Such information will also benefit other cities that are planning to follow Hong Kong's practice of using seawater for municipal purpose. To isolate and characterize the dominant halophilic bacterial species in activated sludge treating Hong Kong's saline sewage. The dominant halophilic microorganisms treating saline sewage differ from those treating fresh water sewage. To isolate and characterize these halophilic bacteria will not only produce scientific information which may lead to improving the performance of Hong Kong's treatment facilities, but also provide useful knowledge for other cities worldwide which are planning to follow Hong Kong's practice. To design DNA probes/primers specific for the identified halophilic bacteria. DNA probes and primers used in hybridization and PCR (polymerase chain reaction) have been increasingly applied to wastewater treatment and study. New DNA probes/primers are needed for the halophilic bacteria treating saline sewage, since probes/primers presently available for bacteria treating freshwater sewage are unlikely applicable. The DNA probes developed in this project will be valuable tools for the study and control of saline sewage treatment. |
