Rainfall-induced slope failure occurs in many parts of the world, especially tropics. Many rainfall-induced failures have been attributed to antecedent rainfalls. Although it has identified as a cause failure, pattern or distribution rainfall not received adequate attention. In this study, parametric studies were performed by using three typical patterns, analysis available data for Singapore and two different soil types represent high- low-conductivity residual soils Singapore. Antecedent...

Granular column is an attractive mitigation method which widely used in geotechnical engineering to enhance the bearing capacity, reduce settlement and accelerate consolidation. Utilisation of industrial wastes such as steel slag soil stabilization can be environment-friendly cost-effective extraction technique disposal solid waste materials. Previous studies investigated capacity ground improved with granular columns or without geosynthetic encasement. However, very limited number have...

Granular columns are widely used to enhance the bearing capacity of weak soil. The filling material is generally stone, gravel or sand. use industrial wastes such as steel slag in civil engineering applications not only reduces environmental pollution, but also leads cost benefits. So far, many studies have been done on behaviour granular with and without geosynthetic encasement under vertical loads; however, very limited were conducted waste lateral loads. Therefore, this study aims...

Abstract Rainfall-induced slope failures frequently occurs in many urban areas around the world especially due to impact of global warming. Some result casualties that have negative impacts on sustainability. The are normally observed near surface within unsaturated zone above groundwater table. Hence, it is important incorporate soil mechanics principles analysing stability during rainfall. This study focuses predominantly regional analyses residual soils Jurong Formation and Bukit Timah...

The unsaturated permeability function is often estimated from the soil-water characteristic curve (SWCC) of a soil. A complete SWCC measurement can improve estimation function. In most laboratories, be measured up to suction 100 kPa using Tempe cell. However, an expensive and time-consuming task. Therefore, this paper presents new approach estimate data points beyond complement kPa. then used proposed uses knowledge grain-size distribution at suction. To verify procedure, tests were...

Abstract Unsaturated permeabilities of six different kaolin-sand mixtures named as 100K0S, 90K10S, 80K20S, 50K50S, 20K80S, and 10K90S were directly measured using a modified flexible wall triaxial permeameter system. 90K10S means that the soil mixture contains 90% kaolin 10% sand by dry mass. Soil–water characteristic curves (SWCC) also for wide range suctions Tempe pressure cell, 5-bar plate, 15-bar saturated salt solutions. The unsaturated estimated ten theoretical models (1) SWCC data...

Post-grouting is a widely used technology for ground improvement and the strengthening of bored pile foundations. In situ experiments have shown that post-grouting effective in improving bearing capacity piles. However, due to cost complexity tests, total number test piles limited. Therefore, it not surprising uncertainty always associated with collected data. This may significantly affect conclusion analyses, most current studies neglected this effect. paper, statistical analyses were...

In transit lines planning, a common issue is that vehicles get overcrowded as they arrive at some intermediate stops. Dispatching portion of vacant to the stops may seem be suitable solution for this problem. This study aimed explaining whether or not can assist in enhancing system performance terms total discomfort users. A mixed integer nonlinear model was proposed by adopting simplifying assumptions. The vehicles' headway and first boarding stop each vehicle were decision variables model....

Abstract The role of diffusion in reducing the saturation pressure oil blocks located at different depths fractured reservoirs has been studied. A model to describe unsteady state a matrix block with given geometry developed and results have compared analytical solution. delay time for solution gas drive due shape calculated by using data Haft kel field.
