刚体极限平衡法与有限元法在工程边坡稳定性分析中的应用与比较

The application and compare of the rigid limit balance method and finite element approach in the slope stability analysis

刚体极限平衡法、有限元法在工程边坡稳定分析中是两个常用的计算方法,文中对两种方法的理论基础和计算过程进行了简要介绍,并应用两种方法对一工程实例进行了分析。结果表明,二者的计算结果相近,且相同工况下有限元计算安全系数略小于刚体极限平衡法计算安全系数。

The rigid limit balance method and finite element approach are always used in the slope stability calculation.The paper introduces their theory basis and calculation process,and their practice in the project. The result indicates their computation result is close,but the safety factor of the former is smaller than the later.
