Analysis of slope stability based on ABAQUS strength reduction method

文章基于有限元强度折减法,以某边坡工程为实例,应用ABAQUS有限元软件对边坡稳定性进行分析,结合特征点的位移突变和塑性区贯通等现象,分析边坡从局部到整体失稳的过程,确定了合理可靠的边坡稳定性安全系数和滑动面位置.并与传统的极限平衡分析法进行了对比分析,验证了ABAQUS有限元强度折减法边坡稳定性分析理论和方法的正确性和有效性.研究成果可为边坡工程设计与施工提供一定的参考.

Based on finite element strength reduction method,taking a slope engineering for example,the slope stability is analyzed by using ABAQUS finite element software.Combining with the displacement characteristics of point mutation and the plastic zone penetration phenomenon,analysing the slope from the local to the whole process of instability,the reasonable slope stability safety factor and sliding surface position is determined.Compared with the traditional limit equilibrium analysis method,the correctness and validity of the slope stability analysis theory and method of ABAQUS finite element strength reduction method are verified.The research results can provide some reference for slope engineering design and construction.
