摘要:
采用极限平衡法和基于有限元的滑面应力法对土坡在超载作用下土坡的稳定性进行了分析。极限平衡法和基于线弹性有限元滑面应力法得出的超载作用下土坡稳定安全系数变化规律基本一致,而采用后者得到土坡的稳定安全系数偏大。基于库伦屈服准则和相关联的流动准则,采用理想弹塑性模型,对土坡在超载作用下的稳定性进行了弹塑性有限元滑面应力法分析。数值计算表明:采用弹塑性有限元分析,土坡在超载作用下,坡顶局部区域内应力场发生了较大调整,从而影响了土坡的稳定性,使得土坡的稳定安全系数下降,最危险滑动面位置上移。
Abstract:
This paper analyzed the stability of soil slope in the condition of surcharge with limit equilibrium method and finite element slip surface-stress method.With limit equilibrium method and linear elastic finite element slip surface-stress method,the relation between surcharge and soil slope stability coefficient were almost similar,but with the latter method,the soil slope stability coefficient was bigger.And also,based on the Mohr-Coulomb failure rule and associated rule,with the elastic-plastic model, this paper analyzed the stability of soil slope in the condition of surcharge with the elastic-plastic finite element slip surface-stress method. Numerical results showed that the stress field in the local area of the soil slope had been modified.This had great influence on the soil slope stability,with the stability coefficient being reduced,and the location of the most dangerous slip being changed.
