Abstract

Abstract: The paper presents evaluation of factor of safety of slope assuming circular failure surface under seismic loading condition. The centre of most critical circle is located using Fellenius method. Adopting limit equilibrium method, under the influence of weight of potential sliding mass and seismic inertia forces, factor of safety is evaluated applying new pseudo-dynamic method based on visco-elastic behaviour of soil which satisfies zero-stress boundary condition and considers soil amplification inherent to soil properties. Results are presented and compared with available results from literature. Detailed parametric studies are also carried out to observe the variation of safety factor at different soil strength and seismic forces and these can serve as very good criteria for design of slopes.
