摘　　要：以水工模型试验为依托,对宽尾墩+消力池联合消能形式中消力池底板的脉动压强特性进行了研究,认为宽尾墩体型、消力池长度、尾坎高度、上下游水位差ΔH及运行方式是影响消力池底板脉动压强特性的主要因素。分析了在各种因素的影响下消力池底板脉动压强特性的变化规律,为宽尾墩+消力池联合消能形式的设计提供了一定的参考。Based on the hydraulic model test,this paper studies the fluctuating pressure characteristics of stilling floor in the form of combination stilling floor with wide end pier energy dissipation.The study indicates that the shape of wide end pier,the length of stilling pool,the height of end bucket,difference of water level between upper and lower reaches and operation mode are the main factors for influencing fluctuating pressure characteristics of stilling floor.Then it summarizes the changing principle of fluctuating pressure characteristics of stilling floor under analysis of the various influencing factors,which provides references for design of energy dissipation.
