摘　　要：红石大坝溢流堰堰型为WES实用堰,溢流坝采用消力斛消能形式。在实际运行中发现,目前的消力斛存在消能效率低,对下游河床及岸坡淘刷严重现象。通过造成破坏的原因分析与模型试验,采用底流与消力池结合的消能方式,实际运行证明,改造后的消能方式改变了原来消能效率低,对下游河床及岸坡淘刷严重的现象,取得了良好应用效果,值得在同类工程中进一步推广应用。The form of Hongshi Hydropower station overflow dam is WES practical weir one,forms of dissipation is roller bucket.There are some disadvantages in actual operation,such as roller bucket efficiency of energy dissipation is low and the downstream river bed and bank are scoured seriously. Though the cause analysis on those destruction and model test,the station combines underflow energy dissipation and stilling basin. New dissipation way changed the above-mentioned defects and it has obtained good application effect in actual operation,this new way is worth further popularization and application in similar projects.
