Abstract :
A permanent landslide due to seasonal stream and rainfall behind Abbottabad Medical Complex has affected residential structures. In this study original and modified slope geometry are selected for stability analysis using the geotechnical parameters evaluated from field and lab tests. Stability analysis are conducted in limit equilibrium program in coupled with saturated-unsaturated seepage analysis in finite element program. The analysis results show that the probability of failure is reduced for modified slope but may not be acceptable. The study further motivates to find additional parameters to design a safe slope for the target area by performing parametrical and sensitivity analysis study.
