三维刚体极限平衡法中荷载的计算方法及工程应用

Load calculation in 3D rigid body limit equilibrium method and engineering application

在三维刚体极限平衡矢量分析法的基础上,探讨了一些常用荷载的计算方法,给出了渗流荷载在不同假定下的算法,包括地下水位的结点设定法和滑块高度折减法。该法已应用于小湾电站进水口边坡的稳定分析,得到了有实用价值的结果。

On the basis of the 3D rigid body limit equilibrium analysis with vector numeric method, the calculations of several common loads are discussed. Especially the algorithms of various assumptions in seepage load calculation are implemented, including node setting method and block height decreasing method in groundwater level definition. It has been applied to the slope stability analysis of Xiaowan Power Station water intake and some results with practical value have been obtained.
