摘要
本文介绍了一个建立在塑性力学上限定理基础上的边坡稳定三维极限分析方法 ,该法将滑动体划分成一系列具有倾斜侧面的条柱 ,引入Mohr Coulumb相关联法则后可求得这些条柱的塑性速度场 ,通过功能平衡方程可算得安全系数 ,采用最优化方法计算临界滑动模式 ,并使用这一方法计算了小湾拱座的稳定安全系数 .
This paper describes a 3\|D slope stability analysis method based on the upper\|bound theory of plasticity. The failure mass is divided into a number of prism with inclined interfaces. The plastic deformation velocity field can be determined based on the Mohr\|coulomb associated flow lay. The factor of safety is obtained by the energy\|work balance equation. The critical failure mode is obtained using the method of optimization. This method is applied to calculate the safety factor of the arch dam abutment in Xiaowan Project.
