摘　　要：收缩式消能工与挑流、底流、戽流相联合的消能方式,在高坝上已获得广泛应用,最近将其应用到中坝上,也取得良好效果。红水河桥巩水电站低坝,作了把收缩式消能工用在低坝戽式消力池里进行混合消能的尝试,水工模型验证结果表明,同样取得显著的消能效果,还使消力戽具有自我清理推移质的能力。<Abstrcat> The energy dissipation by combining contracted type and ski-jump, bottom current and bucket type have been widely used in high dam projects, and its recent application in medium height dam projects also has good effects. For the low dam in Qiaogong hydropower station, a hydraulic model test is done by applying the contracted type and bucket type combined dissipation. The test result not only indicated an obvious energy dissipation effect, but also a self-cleaning capacity of the bucket against bed load.
