| 摘 要： | 结合Geo-Slope软件中的有限元计算模块Sigma/W和刚体极限平衡计算模块Slope/W,将Sigma/W模块中计算所得到的结果导入Slope/W模块,考虑土体的应力-应变关系,利用极限平衡法的概念计算边坡的稳定安全系数并确定最危险滑动面;通过经典算例分析,在极限平衡法中引入有限元计算得应力结果计算边坡的安全系数的方法是可行的,且对均质和非均质的土坡均适用。

| Abstract: | The method combining the finite element computation module Sigma/W and the rigid body limit equilibrium computation module Slope/W of Geo-Slope software is proposed to analyze the stability of soil slope. Considering the stres-strain relation of soil body and leading the results from sigma/w module into slope/w module, the safety factor and the critical sliding surface of the slope are calculated and determined by using the limit equilibrium method. Through the analysis of a classical example, it is found out that it is feasible to lead the results from the finite element method into the limit equilibrium method to compute the safety factor of the slope, and suitable to analyze both the homogeneous and inhomogeneous soil slope. |
