Study on Calculation of Slope Safety Factor by Strength Reduction Finite Element Method

Abstract

One of the main topics of slope stability analysis is to determine the safety factor of sliding surface. In this paper, firstly, the basic principle of finite element strength reduction method is introduced. Then the slope stability is analyzed by the finite element strength reduction method, discontinuous deformation strength reduction method and Spencer method respectively. The results show that the error between them is less than 2%, which indicates that the finite element strength reduction method can be applied to the engineering practice.
