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改善消力池内的水力学指标,但跌坎深度和水流入池角度对其影响较大.因此,如何确定消力池的跌坎高度和水流入池角度是进行消力池设计的关键.The flow pattern, the distribution of average dynamic water pressure and the flow velocity near the floor of lip energy dissipater by hydraulic jump are analyzed through the method of hydraulic test. It shows that the hydraulic index in the baffle basin can be reduced effectively, but they are greatly affected by the depth of lip and the flow intake angle. Therefore, how to ascertain the depth of lip and the intake angle is the key in the design of baffle basin.
