摘　　要：消能工的消能设计对于下游河床的安全有着重要影响,当消力池下游连接斜坡段形成尾坎自由出流时,其消能计算方法尚不完善。根据龙洞水库安全鉴定实例,针对其溢洪道消力池尾坎自由出流的情况进行了消能复核计算分析,可为类似工程提供一定的参考和借鉴。The energy dissipation design of the energy dissipator has an important influence on the safety of the downstream river bed. When the downstream part of the stilling pool connects the slope section to form the free flow of the tail dam,the energy dissipation calculation method is not perfect. According to the safety appraisal case of Longdong Reservoir in Guangzhou City,the energy dissipation check calculation and analysis is carried out for its spillway stilling basin tail dam free flow situation,which can provide some references for similar projects.
