浅析刚体极限平衡法--探讨重力坝深层抗滑稳定的安全判据

本文介绍了各家刚体极限平衡法的理沦和公式。作者认为：按分块形状，它们可分为垂直分块和倾斜分块两类；按滑块间传力的方向，它们又可分为传力方向垂直滑块界面和与界面斜交两类。就重力坝深层抗滑稳定问题，包括刚体极限平衡法的选用，滑移底面和滑块界面强度参数的取值，安全判据以及岩体裂隙连通率的确定等问题进行讨论并提出作者的见解。

Discussion on the rigid body limit equilibrium methods--A probe of the criterion of the gravity dam safety factor against deep sliding stability analysis in the dam foundation

Some authors' rigid body limit equilibrium methods are introduced in this paper. These methods can be divided into two types:the direction of normal force on the plane between two slices is perpendicular or inclined to the plane. They can also be divided into two types according to the shape of slices:vertical or inclined slices. The problems of gravity dam slide on the underground planes including the selections of calculation method, strength parameters, continuity percentage of rock mass on the slip surface, interface of slices and the criterion of safety factor etc. are discussed in this paper.
