Analysis of stability of plug for diversion tunnels;

导流隧洞堵头稳定性分析

By using 3D nonlinear finite element method,the stability against sliding of the plugs of diversion tunnels of Shuibuya Project with different gullet depth and different length is carried out.

采用三维非线性有限单元法,对水布垭导流隧洞堵头进行了不同齿槽深度、不同堵头长度下的堵头稳定分析,然后基于分析结果提出了堵头体型优化建议,使堵头长度由初步设计的45 m减少到31 m;最后根据实际施工情况进行了施工期的堵头反馈设计与稳定校核。

The stability of the diversion tunnel plug is important.

在抗剪断理论的基础上采用非线性有限元分析方法,对某水电站导流隧洞堵头进行了三维有限元计算,并对堵头结构特征位置的应力、变形以及堵头整体的抗剪断安全系数等方面展开了深入分析。
