摘要

目前，在边坡稳定性分析中广泛地采用二维极限平衡分析方法进行研究。但是对于地形、地层、地下水、岩体结构等条件复杂的边坡，仅用二维极限平衡分析方法进行研究是不够的，二维分析忽略了边坡的三维效应，而复杂边坡往往受三维效应影响大。但至今三维极限平衡方法还不是很完善。因此，本文结合一工程实例，采用二维与三维极限平衡分析相结合的方法对其边坡的稳定性进行了分析。研究结果表明，对于复杂边坡，应用二维和三维稳定性分析相结合的方法进行研究是一种较为恰当的选择。

Abstract

In current slope engineering

2D limit equilibrium method is widely used. But it isn’t enough for slopes with complex conditions of geology

groundwater

rock structure etc. 3D effect is ignored in 2D analysis

while it has great effect on complex slopes. However

3D limit equilibrium method is not perfect at present. Therefore

a synthetical method of using both 2D and 3D limit equilibrium methods is proposed to analyze a practical slope stability. The result shows it is a good method for complicated slopes.
