江坪河高面板堆石坝三维非线性结构有限元分析

3D nonlinear finite element analysis of Jiangpinghe Concrete Face Rockfill Dam

采用三维非线性有限单元法对江坪河面板堆石坝施工填筑期和水库蓄水运行期的应力变形进行模拟计算 ,研究引用不同的堆石料参数 (水布垭面板坝和天生桥一级电站面板坝材料参数 )和不同的接缝单元模型 ,分析不同时期产生的坝体应力和变形。且对江坪河面板坝与水布垭和天生桥面板坝的应力和变形特性做了对比分析 。

In this paper, a three dimensional nonlinear finite element analysis is adopted to calculate and simulate the stresses and deformations of the Jiangpinghe Concrete Face Rockfill Dam from its construction to operation period. In the study, the different parameters of rock filled materials (the materials used for the dams of the Shuibuya and Tianshengqiao First cascade rockfill dam) and different interface element models have been adopted. The stresses and deformations of dam body in different stages have been analyzed. The respective results are compared and analyzed among the Jiangpinghe, Shuibuya and Tianshengqiao concrete face rockfill dam. Finally, the authors give some useful suggestions to the further more reasonable design work.
