In this paper the progress in analysis on slope stability by limit equilibrium and finite element methods was introduced. Based on limit equilibrium, an equation for calculating the safety factors of stability of multi step slope and the angle of sliding surface has been derived, which is important for design of rock slope. A united equation for present various slice methods has been derived. For non strict slice method the safety factor can be obtained by one equilibrium equation given the orientation of force action between the slices. For strict slice method the safety factor can be obtained by two equilibrium equations given the orientation or the point of force action between the slices. The united equation is a simple iterative one and the calculation can be performed simply with high accuracy. Two methods for obtaining safety factors of slope stability by FEA have been presented. One of which is based on the limit equilibrium method with arch search for soil slope and arrangement of joint element on sliding surface for rock slope. The another one is a strength reduction of finite elements for application of large software, which is a new method for safety factor of slope stability. [

本文介绍近年在用极限平衡法与有限单元法 ,分析边坡稳定性方面的一些进展 ,在基于极限平衡的解析法上 ,我们导出了多阶斜坡的稳定安全系数与滑裂面角度的计算公式。这对岩质边坡的设计有很高的实用意义。导出了目前采用的各种条分法的统一计算公式。对于非严格条分法 ,用一个平衡方程并假设条间力的作用方向 ,即能求得安全系数 ;对严格条分法 ,用二个平衡方程 ,并假设条间力的作用方向或条间力的作用点位置 ,就能求出安全系数。统一式是一简单的迭代式 ,因而计算简便 ,并有很高精度。提出了两种用有限元法求边坡稳定安全系数的方法 :一种基于极限平衡法 ,对土质边坡采用圆弧搜索法 ,对岩质边坡采用在滑移面上布置节理单元的方法。另一种采用有限元强度折减法 ,便于采用大型软件 ,是一种很有前途的求边坡稳定安全系数的新方法。
