摘要
台阶式溢洪道在国外许多碾压混凝土坝上得到采用，本文通过试验，分析了台阶式溢洪道的消能特性、单宽流量与消能率的关系，以及台阶面坡度对消能率的影响，以便探讨在我国碾压混凝土坝上应用台阶式溢洪道的前景．
With the development of RCC dam, stepped spillways are used in many RCC dams. Ahydraulic model investigation was conducted to evaluate the per formance of a stepped spillway, andthe effectiveness of energy dissipation due to slope of the spillway face, and to evaluate possibility ofapplication in RCC arch dams.
