摘　　要：基于宽尾墩消力池泄洪消能的水工模型实验,在不同泄流量、闸门开度和下游水深的条件下,研究不同池长消力池的泄洪流态、流速分布、消能率以及消力池底板压力等水力特性,比较了不同池长消力池的消能效果。试验证明:在尺寸相对较长的消力池中,可达到较好的消能效果。This paper makes a study of such hydraulic characteristics as flow pattern of flood discharging, distribution of flow velocity, rate of energy dissipation and bottom plate pressure of a plunge pool with different lengths under different flood discharges, gate openings and downstream water depths based on hydraulic model test for flood release and energy dissipation of a flaring pier plunge pool and then makes a comparison between the plunge pools with different lengths in terms of energy dissipation effect. The test has proved that a longer plunge pool can bring about better energy dissipation effect.
