摘　　要：近年来,随着人们环境保护意识的不断增强,许多大型水电工程的泄洪消能倾向于采用泄洪雾化较低的底流消能方案。然而,经济和技术两方面的因素制约了底流消能在高水头、大流量水电站建设中的应用。针对底流消能应用于高水头、大流量泄洪工程时存在的问题,在总结已有研究成果的基础上,结合国内向家坝、官地和亭子口以及国外某些高坝工程泄洪消能实践,对跌坎底流消能工的研究进展进行了综合分析。可为类似工程的体型优化设计提供参考。Nowadays, with the increasing awareness of environmental protection, a number of large hydropower stations tend to use underflow energy dissipater that has low atomization effect. However, economic and technical factors have restricted its appli-cation in hydropower projects with high water head and large discharge. According to the problems in its application, the research achievements are summarized. Combining with the engineering practice of step - down floor underflow energy dissipater at Xiangjiaba, Guandl and Tingzikou hydropower stations and the hydropower stations abroad, we conduct a comprehensive study and summarization on the research achievements.
