摘　　要：在高水头压力输水管道中,为满足一定的流量要求,闸门开度通常不宜太小,此时将导致管道内部及出口水流仍然具有比较大的流速和动能,从而引发管道空蚀破坏或严重淘刷下游,直接危及工程安全。现结合工程实际,在管道进出口联合采用三级突扩消能设施,既很好地解决了管道消能问题,也保证了一定的过流能力,可为同类工程参考。In a high head penstock, if the gate opening is too small, it is impossible to meet discharge demand. There will be a relatively large velocity and high kinetic energy in the pipeline, possibly causing the pipeline cavitations damage or severe erosion downstream, directly endangering the safety of the facility concerned. In this paper, a description is provided of equipment which creates a three- stage- diffusion of energy applied at both ends of the pipeline. The application of this equipment can diffuse energy in the pipeline and guarantee the sufficient discharge of water.
