摘　　要：主要介绍了金平水电站竖井溢洪道出口台阶消能方式、消能工的布置及运行情况,阐述了台阶式消能工的消能原理及消能率,结合水工模型试验成果及实际泄洪情况对金平台阶消能进行了总结,结果表明:台阶消能工消能率在80%以上,台阶上不发生空蚀,大大减轻了下游消能压力。The terraced energy dissipater behind the outlet of the shaft spillway in Jinping Hydropower Station and its layout and the operation status are introduced. Energy dissipation principles and the dissipation ratio of the terraced dis- sipater is presented. Results of the hydraulic model experiment and the actual performance of the Jinping terraced energy dissipater show that the energy dissipation ratio of such dissipater is over 80% and cavitation is not observed on the dissi- pater steps, which relieves the pressure of downstream energy dissipation greatly.
