一、引言 边坡稳定分析的极限平衡方法自从十九世纪初以来有了很大的发展,相继产生了众多的计算方法。这些方法的共同点是:(1)以莫尔——库仑强度理论为基础;(2)滑体处于静力极限平衡状态;(3)应用有效应力原理;(4)没有考虑滑体的应力——应变特性。根据每种方法的适用条件和分析方式可将它们分为三大类; I. INTRODUCTION The limit equilibrium method of slope stability analysis has been greatly developed since the beginning of the nineteenth century, and many calculation methods have been successively produced. The commonalities of these methods are: (1) based on the Mohr-Coulomb’s strength theory; (2) the slide is in static equilibrium equilibrium; (3) the effective stress principle is applied; (4) - Strain characteristics. According to the applicable conditions and analysis methods of each method, they can be divided into three categories;
