摘　　要：低水头、低佛汝德数消能一直是中小型水利工程泄洪消能的关键问题,通过水力学模型试验方法,对安宁水电站溢洪道泄洪消能问题进行了研究。结果表明:通过折坡消力池中布置两排消力墩以及护坦末端加设尾坎的方案,解决了该溢洪道消力池消能及水流衔接问题,提高了消能率,改善了下游河道水流条件。The low head and low Fr number of consumers have been a key issue in flood discharge and energy dissipation of middle and small hydraulic engineerings.Through hydraulic model test methods,the energy dissipation in Anning Hydropower Station＇s spillway were studied.The results of the study show that the arrangement with two rows of the stilling piers and a tail threshold at the end of the apron in the stilling basin with inflection could solve the problems of the stilling basin＇s energy dissipation and flow convergence of the spillway,increase the energy dissipation rate and improve the flow state in downstream river channel.
