摘　　要：　对鸭池河水电站引水系统坝后背管进行了三维有限元分析,得出了背管在死水位、正常蓄水位、校核洪水位及温变作用等工况下产生的应力及位移,为该钢管设计及施工提供了依据.根据分析计算结果,提出了取消伸缩节的建议,可大量节省投资成本.In this paper, 3-D FEM(Finite Element Method) is adopted to analyze the stress and displacement of the penstock on downstream dam surface in the Yachihe Hydropower Station when the station is in operating conditions of dead water level, normal water level, and maximum flood level at different temperature conditions. The results obtained in the analysis form basis for the penstock design. Based on the analysis, the expansion joint of the penstock is suggested to be eliminated to reduce the cost of the penstock.
