摘要：

极限平衡法与有限元强度折减法是目前边坡稳定分析计算中常用的两种方法。以中东某混合坝边坡稳定计算为例，该混合坝基础内存在软弱夹层，采用极限平衡法与有限元强度折减法对边坡稳定性进行计算，总结分析两种方法的计算结果及差异，并对分析方法进行探讨。结果表明：极限平衡法和有限元强度折减法求解得到的安全系数较为接近，均可对含软弱夹层边坡进行模拟。

Abstract: Limit equilibrium method and strength reduction FEM are two commonly used methods in slope stability analysis and calculation. The slope stability calculation of a mixed dam in the Middle East is taken as an example, which has a weak intercalation in the foundation. The limit equilibrium method and strength reduction FEM are used to calculate slope stability, and the calculation results and differences between two methods are analyzed. The results show that the safety factors obtained by limit equilibrium method and strength reduction FEM are close to each other. The two methods can both be used in simulation of slope with weak intercalation.

Key words:

stability analysis of the slope, limit equilibrium method, strength reduction FEM, weak intercalation
