Abstract

A procedure to determine the factor of safety of a slope using finite element method in conjunction with genetic algorithm is proposed. The stresses in soil are obtained using finite element method whereas the critical slip surface is located using genetic algorithm, an optimization technique. The applicability of the procedure is proven by analyzing three non-homogenous slope examples and compared with those available in the literatures. It is observed from the results that the proposed technique provides better solution in terms of determining the minimum factor of safety compared to the other methods. In finite element analysis the influence of modulus of elasticity and Poisson’s ratio on factor of safety for slope 1 is studied and the effect is visible.
