Abstract

The analysis and design of failing slopes and highway embankments requires an in-depth understanding of the failure mechanism in order to choose the right slope stability analysis method. In the present work, the concept and theory involved in different methods of slope stability analysis of earth embankment have been discussed. The mathematical equations and the methodology for calculating the factor of safety of earth slope of any specified (chosen) slip circle by various methods has been given. By repeating the process for different slip circles, the minimum factor of safety can be calculated and critical slip circle obtained. A simple example of earth embankment has been analyzed to illustrate the methodology with the help of Microsoft Excel program for various methods and the values of FOS resulted are compared.
