基于强度折减有限元法的边坡稳定性计算

A Modified Mesh Partition Method with P-FEM for Slope Stability

弹塑性有限元强度折减法是一种非常有效的边坡稳定性计算方法,从增量有限元方程出发,分析了该方法的特点,并且讨论了滑动面的确定方法和失稳破坏特征,并通过对一具体工程的边坡稳定性计算,表明该方法简单有效,对实际工程具有很强的指导意义。

The elastic-plastic strength reduction FEM is a very effective method for the slope stability analyses.This paper begins with the FEM increment equation and analyses characteristic of the method,and then makes a discussion of how to determine the sliding surface and the characteristic of unstable failure.Finally,there is an engineering example of the slope stability computation which show that the elastic-plastic strength reduction FEM is very simple and effective,and has guiding significance for practical engineering.
