【Abstract】 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.更多还原
