基于ABAQUS二次开发平台的边坡有限元强度折减法研究
Research on the strength reduction FEM of the slope by applying the secondary development platform of ABAQUS
摘要
Abstract
The strength reduction FEM plays an important role in the slope stability analysis.But the strength reduction FEM often gets the safety factor of slope by the dichotomy,which is less efficient because of its need for trial.With the secondary development platform UFIELD program of ABAQUS,the strength reduction FEM based on the field variable is realized by defining the field variable of the software as the reduction factor and establishing the relationship between the time step and strength parameters and field variable.This method only submits an analysis to cal-culate the safety factor of the slope effectively.Based on the principle that the equivalent plastic strain of the sliding zone is maximum,the searching for the location of the potential slip surface of the slope is realized using point by point searching method of different vertical profiles.Final-ly,taking the two typical slope as examples,the comparative analysis of the potential slip surface and safety factor is made by the traditional limit equilibrium method of M-P and the method pro-posed in this paper.Thus,the validity of the method proposed in this paper is verified.关键词
