摘　　要：介绍了库什塔依水电站引水钢岔管振动时效处理的原理、工艺,以及消除焊接残余应力的效果;分析了振动时效处理过程中出现的一些问题,讨论了岔钢管振动时效处理的注意事项;提出了改善振动时效效果的途径。确认在合适的工艺条件下,采取振动时效方法消除或均化引水钢岔管的焊接残余应力是切实可行的。The principle and process of Vibrating Stress Relief （VSR） of diversion steel bifurcated pipe in Kushitayi Hydropower Station and the effect of VSR are introduced. The problems emerged in the VSR treatment are analyzed and the precautions in VSR treatment are discussed. The ways which can improve the effect of VSR are also proposed. The practice in Kushitayi Hydropower Station shows that eliminating or homogenizing welding residual stress of diversion steel bifurcated pipe by VSR is feasible.
