摘　　要：采用水力学试验方法,对跌坎型底流消能工的水流流态、时均动水压力分布以及临底流速进行了分析。并对影响消力池水力特性的跌坎深度和水流入池角度进行了研究。研究表明跌坎型底流消能工能有效解决高水头、大单宽流量消力池水力学指标过高的问题。The flow pattern, the distribution of time-average hydro-dynamic pressure and the flow velocity near the floor of the energy dissipator with step-down floor are analyzed with the hydraulic experiment concerned; in which the depth of the step-down floor and the flow intaking angle affecting the hydraulic characteristics of the stilling basin are studied as well. The study results show that the problem of over-high hydraulic indexes of the stilling basin of high head and large unit-width discharge can be solved with energy dissipator with step-down floor.
