摘　　要：采用弹塑性有限元 ,对三峡水电站引水钢管焊接残余应力进行了计算。计算结果与相关资料吻合 ,从而为引水钢管取消伸缩节的设计 。Using elastoplastic finite elements, it is computed that the welding residual stress of guidewater steel pipes in the Three Gorges hydroelectric station. The calculated results agree with the related references, therefore it provide the theoretical consult for the design of the guidewater steel pipes replaced the expansion joint.
