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 ,提供了理论参考
Using elastic-plastic finite element method, the welding residual stress of the water intake pipe of Three Gorges Hydropower Station was calculated. The calculated results are in good agreement with the relevant data, which provides a theoretical reference for eliminating the design of telescopic joints in water-filled steel pipe
