摘要 通过建立整体计算域的三维非线性有限元网格 ,用有限元方法分析研究了宝珠寺水电站拦河大坝左岸河床坝基下的楔形体对坝基深层抗滑稳定性的影响程度 .为验证大坝整体有限元网格的计算精度 ,在大坝整体有限元网格的基础上 ,局部进行了有限元网格的细分 ,粗细网格的计算结果得到较好的吻合 。 By establishing the three dimensional mesh of the global calculation domain, the FEM is used to analyze the influence of the rock wedge under dam foundation of the river bed by the left bank of the Baozhushi Hydropower Project on the deep sliding stability of rock foundation. To check the accuracy of calculation, based on the global one, the meshes of the 19th to 21st dam blocks are locally densified. The results from the locally densified mesh are compared with that from the global one. The coincidence of the two results demonstrates the adequacy of accuracy of the global mesh.
