摘　　要：溢洪道消力池的消能问题是保障泄洪安全的关键,特别是极低下游河道水位给消能布置带来更大的难度.结合某高水头水库工程岸边溢洪道,采用物理模型试验的方法,分析了下游极低水位消力池布置与流态衔接方法;研究成果建立了下游河道水深、消力池池深与水跃跃后水深的控制方法,提出了优化消力池流态的工程措施.Energy dissipation problem of the spillway stilling pool is the key to ensuring the safety of flood discharge.Especially the extremely low downstream river water level brings greater difficulty to the energy dissipation layout.Based on a high head reservoir project,this paper analyzes the layout and flow pattern connection method of the downstream very low water level stilling pool using physical model tests.The research results have established control methods for downstream river depth,stilling pool depth,and water depth after hydraulic jump,and proposed engineering measures to optimize the flow pattern of the stilling pool.
