摘　　要：结合某高水头水电站工程的实际,采用了一种考虑初始缝隙的埋藏式钢岔管有限元分析方法,即将围岩简化为在有限元节点上施加纯压缩弹性抗力的模型,对钢岔管与围岩联合承载结构进行了有限元计算和分析,计算结果表明,围岩对钢岔管应力的影响和减小钢板厚度的效果十分显著。In accordance with the practice of a hydropower station with high pressure, finite element method is used to analyze the stress and deformation of an underground steel bifurcation with gap existing between bifurcatio n and surrounding rock, in which the rock is considered to evoke elastic reactions to the bifurcation. The FEM analysis result of underground bifurcation indicates that rock has a great effect on bifurcation stress and can therefore reduce the thickness of the bifurcation.
