以桐子林水电站导流明渠框格式地下连续墙及导墙结构为研究对象，根据其真实的地质条件建立了三维有限元模型。基于 ABAQUS 有限元软件，采用 Mohr-coulomb 屈服准则、非关联流动法则，对水平推力最大的工况下的框格式地下连续的施工过程进行了模拟，详细分析了不同的嵌岩深度对墙体变形和应力的影响。由于框格式地下连续墙整体刚度较大，增加嵌岩深度对墙体的变形趋势影响较小，墙体的大部分应力有较大程度的改善，会增加局部位置的应力，对结构的整体稳定有利。可供类似工程借鉴。

Taking the sash-shaped underground continuous wall and guide wall of the diversion channel of Tongzilin hydropower station as the object of research, and based on the real geological condition, a three-dimensional FEM model was established. Using ABAQUS software, Mohr-Coulomb failure criterion, and non-associated flow rule, the construction process of the working condition with the largest horizontal thrust, the influence of the rock-socket depth to the deformation and stress were analyzed in detail. Because the overall stiffness of the sash-shaped underground continuous wall is rather large, to increase the rock-socket depth has little effect on the deformation trend. Most of the stress of the wall will be improved in a great degree, and it will increase the stress in some local position. It can benefit the overall stability of the structure. The result can be used as references for similar projects.
