摘　　要：通过对某大型水电站进行三维有限元计算分析 ,得出了厂坝间垫层管的变位及受力情况 ,为取消厂坝间压力钢管伸缩节提供实际工程论证 ,并提出了取消厂坝间伸缩节后所应采取的有利结构措施和施工过程 。Through the three dimension finite element analysis on the large hydropower station, this paper obtains the displacements and stress conditions of the penstocks with cushion layer between the powerhouses and dams. It can be used as practical project evidence. This paper also puts forward some favorable structural measures and constructral process, which should be adopted after canceling the contraction joints. It is a good example for the construction of the same kind of the projects afterwards.
