摘　　要：通过模型试验，对台阶式溢洪道滑行水流的时均压强特性进行了研究，探讨了台阶上时均压强的产生和变化规律。同时探讨了来流量、台阶尺寸等因素对台阶上压强变化的影响。对于工程的设计，施工都具有很好的参考价值。The characteristics of time average pressure of skimming flow in stepped spillway are studied through experiments, and the law of occurrence and transformation are discussed. The factors influencing the pressure fluctuation on steps are analyzed, such as runoff, dimension of steps. The result has reference value for the design and construction of stepped spillway.
