Abstract: Hydraulic fracturing in clayey soils can be triggered by either tensile or shear failure. In this paper, the physical meanings of various equations to predict fracture initiation pressure proposed in the past are discussed ...

Abstract: In recent years wireless sensors are becoming more widely used to monitor water distribution systems in the water supply industry. When sensors are installed in areas where electric power supply is lacking and/or battery ...

Abstract: This study proposes a novel optimal isolation valve placement method for water distribution networks (WDNs) using dynamic programming. The proposed method automatically finds the best places to install isolation valves ...

Abstract: AbstractA water distribution network (WDN) requires the closure of isolation valves to isolate malfunctioning pipes from the system. As water infrastructure ages, the condition of isolation valves is deteriorating. However, ...

Abstract: Pile groups are frequently designed with equal or similar pile lengths. However, the significant interaction effects among equal-length piles imply that this may not be the optimized configuration. This paper presents the ...

Abstract: Microbially induced carbonate precipitation (MICP) using ureolytic bacteria shows promise in the field of geotechnical engineering for several different applications, such as ground improvement and groundwater control. ...

Abstract: This paper describes a new formulation of the material point method (MPM) for solving coupled hydromechanical problems of fluid-saturated soil subjected to large deformation. A soil–pore fluid coupled MPM algorithm based ...

Abstract: Compensation grouting is often employed as a mitigation technique to reduce the settlements induced by tunneling. The efficiency of compensation grouting, defined as the ratio of the volume of heave induced at the ground ...
