| 摘 要： | 本文通过建立某边坡的模型，分别采用基于有限单元法的强度折减法与刚体极限平衡法，对该边坡的原始状态以及三种不同开挖方案下边坡的稳定性进行了分析，得到了相应的边坡最危险界面及其稳定系数。计算结果表明：两种方法计算结果接近，刚体极限平衡法计算边坡的稳定系数均大于有限单元法结果；边坡坡角的减小可以有效提高边坡的稳定系数。计算结果为边坡开挖方案设计提供了参考依据。

| Abstract: | In this paper slope models were established, using based on the finite element method of strength reduction and rigid body limit equilibrium method to analyze the original state of the slope stability and three different excavation schemes slope stability, getting the corresponding interface and the most dangerous slope stability factor. The results show that two methods of calculation were very similar, the coefficient of stability in rigid body limit equilibrium method was bigger than that in the finite element method for calculating side slope stability. The reduction of the angle of side slope could increase coefficient of stability .The result of the analysis provides reference for side slope excavation schemes.Key words: side slope stability; the finite element method; strength reduction method; rigid body limit equilibrium method |
