Analysis of slope considering circular rupture surface

Abstract

Determination of stability under seismic loading condition of soil slope is one of the important findings for geotechnical engineers. Here, in this paper, a homogeneous soil slope considering circular failure surface has been analyzed under the influence of pseudo-dynamic inertia forces and surcharge load by limit equilibrium method. The Fellenius line is used to locate the center of most critical circle and factor of safety has been found through the application of force equilibrium. The effects of variation of parameters such as horizontal and vertical seismic accelerations, soil friction angle and slope angle on factor of safety are presented.
