DESIGN OF TRENCH DRAIN FOR STRATIFIED SOIL USINGN FEM

Abstract

Large number of landslides occurs quite often during rainy seasons primarily owing to the development of substantial pore water pressure in a slope mass. Rainfall induced failures are the most common ones causing many landslides. There is a need for developing suitable methodology for examining the effectiveness of different stabilizing techniques to be adopted. By applying hydraulics and seepage analysis we can develop different measures for controlling the occurrences of most of the landslides. To prevent the occurrence of landslides, trench drains are widely used for draining out water from the soil and to reduce the pore water pressure to restore stability of the slope. Current project explains hazard ness of landslides, importance of hydraulics and seepage analysis in providing design guidelines of trench drains by numerical and statistical data. In this aspect we obtained variation of seepage velocities of the trench for various values of depth in a stratified soil medium by us...
