Scope and Objectives

In many cases landslides occur owing to the development of excessive pore water pressure in soil mass. Trench drains are one of the remedial measures for draining out water from the soil and to reduce the pore water pressure to restore stability of the hill slope.

This work has been dealt with multilayered soil to investigate the piezometric levels, velocities and discharge of water flowing into the trench drains.

 
Methodology
Finite element method (FEM) has been used for investigating the performance of two dimensional steady state flow of water within a parallel rectangular trench drainage system for multilayered soil. Finite Element Software has been developed for multilayered soil. Based on the FEM, numerical results are obtained for various combinations of the soil. Illustrations are to be developed from the numerical results to draw the new findings.
 
Findings and Conclusions
Work is continuing.
