Slope Stability Analysis Using Oasys Slope

Aims and Objectives.

The main aim of this project is to analyze the factor of safety of the land slope using various methods such as conventional method, Finite Equilibrium method etc,. By the use of Monte Carlo methods, the analysis output is obtained. The comparison of factor of safety achieved by various methods are analyzed and discussed. A slope stability software Oasys is used for the development of curves and the slope failures.
