摘　　要：针对酉酬水电站坝址河谷狭窄、岸坡陡峻,河道平直,洪水峰高量大,下游消能防冲问题较为突出的问题,对戽流消能与底流消能型式进行了比选,通过水力学计算、模型试验对比分析,推荐采用宽尾墩加底流消能型式。消能防冲建筑物投运后,通过泄洪观察,消力池池尾水流平顺,宽尾墩后水流掺气明显,消能效果良好。The downstream energy dissipation and scour protection is a serious problem in Youchou Hydropower Station due to its characteristics of narrow valley,steep riverbank slope,straight river channel and high flood peak discharge.The design of energy dissipation structures are introduced. With the hydraulic calculation and model experiments,the submerged bucket energy dissipation and the underflow dissipation are compared. Then,the underflow dissipation type combined with flaring piers is selected. Satisfactory energy dissipation effect is observed in practice that the discharge flow is smooth in the end of the stilling pool and flow aeration is obvious behind the flaring piers.
