| 摘 要： | 构皮滩水电站设计中采用弹塑性有限单元法对右岸水垫塘峡谷出口区边坡施工开挖进行了仿真模拟计算，对边坡的变形、应力状态、塑性区分布等进行了分析评价。计算结果表明：边坡整体是稳定的，但坡脚部位分布有一定范围的压剪屈服区，对该部位应加强支护。计算成果对边坡的合理支护具有一定的指导作用。

| Abstract: | In the design of Goupitan Hydropower Station,using elastic-plastic finite element method,the writers carried out a simulation calculation to the excavation on the slope of valley mouth area of cushion pool on the right bank,as well as analysis and appreciation on deformation of the slope,stress status and distribution of plastic area.The results make known that the slope as a whole is stable,but a pressure-shear yield area distributes at certain scope of the slope foot.Support to the area,therefore,should be strengthened.The results of calculation have some directive functions to reasonable support of slope. |
