Stability Analysis of Geotechnical Slope Based on Strength Reduction Method

Abstract

In order to overcome the problems of large analysis error and low analysis efficiency in the current analysis method of rock and soil slope stability, a new research method based on strength reduction method is proposed in this paper. On the basis of the finite element analysis method, the finite element model is established, including the establishment of geometric model, preparatory work, and the fast triangle algorithm is used to optimize the mesh constructed by the finite element optimization method, and the mesh quality is tested. Secondly, the strength reduction method is used to analyze the advantages of geotechnical slope stability, and the established finite element model is solved by using the strength reduction method to obtain accurate geotechnical slope stability coefficient and complete the accurate analysis of geotechnical slope stability. The experimental results show that compared with the traditional method, the stability coefficient calculated by this method is closer to the actual data, with lower analysis error and higher analysis efficiency, and the maximum analysis time is only 2.5 s.
