| 摘 要： | 采用弹塑性有限单元法对构皮滩水电站水垫塘高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,但各级边坡的坡顶部位存在一定范围的拉应力区,坡脚部位分布有一定范围的压剪屈服区,对这些部位应加强支护.计算成果对边坡的合理支护具有一定的指导作用.

| Abstract: | Based on the elastoplastic finite element method, stability analysis of the high slope at the spillway of Goupitan Hydropower Station is carried out with simulating the construction process. Meanwhile the deformation, the stress and the distribution of the yield zones are evaluated. The results show that the slope is safety, at the same time the tensile stress zone at the top and the compress-shearing yield zone at the bottom of each step should be strengthened. The results provide a valuable reference for reasonably supporting the slope. |
