| 摘 要： | 提出了一种土坡抗震稳定性分析的新方法，即将有限元法和传统的滑动面法相结合。首先根据有限元法通过求解动力方程，计算出某一时刻土坡内的有效应力，然后根据有效应力计算该时刻的最危险滑动面及对应的安全系数。该方法不仅能够考虑土的应力应变性质，而且能够在任意时刻确定最危险滑动面的位置及安全系数。给出了该方法的详细算法。

| Abstract: | A new method for analysis of slop stability to earthquake is presented.The method combines finite element method (FEM) with traditional slip surface method,and is divided into two steps:first,based on the FEM,the effective stresses in slop are determined by solving dynamic equilibrium equation at some time;second,determining the most dangerous slip surface and its factor of safety at this time by using the effective stresses calculated in the preceding step.The method not only can consider behavior of stress strain of soil,but also can determine the most dangerous slip surface and its factor of safety at any time.The detailed algorithm of the method is also given. |
