摘　　要：以某水利水电枢纽工程为例 ,分别对明岔管和有初始缝隙的埋藏式钢岔管两种结构方案 ,进行了三维有限元计算分析 ,讨论了围岩性能及初始缝隙值对钢岔管应力和围岩承载比的影响 ,并与明岔管计算结果相比较 ,得出了一些有意义的结论。Through illustration of a hydropower project, three-dimensional finite element analyses of two structure schemes of exposed bifurcation and the embedded bifurcation with initial gap are carried out. The influences of surrounding rock performance and initial gap value on the stress of steel bifurcation and bearing capacity of surrounding rock are also discussed. Some significant conclusions are drawn through comparison of calculation results between the two schemes.
