| 摘 要： | 基于断裂力学、极限平衡理论建立推移式滑坡的破坏模型,利用有限元软件ANSYS对计算模型进行模拟,搜索到最危险滑动面,并认为滑坡是沿其贯通的。数值模拟的结果与推移式滑坡的实际破坏状态是比较吻合的,本方法对其他类型的滑坡形成机理的研究也有一定的借鉴作用。

| Abstract: | Based on fracture mechanics and the limit equilibrium theory,the paper established thrust load caused landslide damage model,Using ANSYS finite element software,simulated the calculation model,and searched for the most dangerous slip surface and thought that the landslide was along its link up.Numerical simulation results with the actual thrust load caused landslide damage state are relatively.This method of analysis of mechanism in other geological disasters also has a certain degree of reference. |
