地下埋藏式钢岔管结构三维有限元分析

3D finite element analysis of underground embedded steel bifurcation structure

目前对于地下埋藏式钢岔管结构设计还没有一个指导性准则,对于其工作运行状态研究也不够,因此对地下埋藏式钢岔管结构进行数值分析是一个非常重要又亟待研究的课题。为此,根据钢衬、混凝土衬砌与围岩的联合承载特点,对水电站地下钢岔管结构采用三维有限元方法进行了分析计算。得出的成果可为埋藏式钢岔管的设计提供一定的参考。

The analysis of undergroundembedded steel bifurcation structure is a fairly important problem, also urgent to solve. Based on the study of automatic meshing of the bifurcation, numeric analysis of undergroundembedded steel bifurcation structure has been carried out in this paper. During the finite element analysis, the combined effect of the liner of bifurcation with the surrounding rock is considered, the result is satisfactory, can provide reference for the practical design of undergroundembedded steel bifurcation structure.
