摘　　要：青海仙米水电站原设计方案中的消力池入池单宽流量大、流速大、消力池长度不够、消能不充分.经多方案设计比较和试验研究,采用掺气分流墩设施后,消力池中的水流非常平稳,跃后水深也有较大幅度地降低,消力池长度减小了20.0 m,尾坎高度也降低了1.0 m.The unit inflow rate, velocity to tumble bay is rather large, but the tumble bay not long enough with inadequate energy dissipation in the original design scheme for Xianmi Hydropower Station. It is shown by research and model test that when the aerifieation diffluenee pillar used, the flow in tumble bay is very placidly, the depth after iumping decreased largely, which result in the length of tumble bay shorten 20. 0 m, the height of end ridge fall down 1.0 m.
