Soil slopes can be either natural or manmade. Design and study of soil slopes involve a critical activity, i.e., analyzing its stability. Ascertaining the stability can help preventing a slope failure and also help in redesign of failed slope. It involves identifying the critical failure surface approximately and determining corresponding Factor of Safety. Analyzing the stability of slope is an iterative process. Different analytical methods with manual calculations have been developed based on soil strength parameters. Stability of slope is ascertained by means of factor of safety to a slope’s critical failure surface. With advent of software programming, computer modeling, analyzing and examining slope stability problems for the different analytical methods developed has become an easy task. In the present study, a renowned geotechnical slope stability software Slope/W was used. The study involved modeling of homogenous soil slopes with different values of critical slope stability parameters such as cohesion (C), soil’s unit weight (γ) and internal friction angle (Ø) to each of the four assumed slope configurations. Identification of slope stability was done by determining the critical slip circle of failure through Bishop’s method of analysis in Slope/W software program. Overall 128 models were analyzed and the research findings for the above data were compared. Results showed that for a given slope configuration, the factor of safety changes with changing cohesion, soil’s unit weight, and internal friction angle. Also slope’s factor of safety changes in boundary conditions from dry to partly saturated for a given slope configuration and corresponding slope stability parameters.
