摘　　要：大藤峡水利枢纽泄水建筑物具有库水位变幅大、单宽流量大、尾水变幅大等水流特性和闸下水流拍打钢梁、推移质过坝的运行特点,消能形式选择限制因素多,消能问题非常复杂。对大藤峡水利枢纽二级逆坡分区消力池布置演变过程进行阐述,给出枢纽典型工况泄洪消能调度与闸门调度原则,可供类似工程参考。The discharge structures of the Datengxia Reservoir have water flow features of wide variation of water level,big flow of reservoir width and big changes of tail water,as well as operating characters of flow downstream from shiplock patting steel beam and bedload passing though the dam.Energy dissipation becomes more complicated due to the restriction factors for the selection of energy dissipation methodologies.Based on examination of evolution of stilling pool arrangement of the secondary reverse slope zoning of the Datengxia Dam,principles are defined for standard conditions to regulate flood discharge or energy dissipation and sluices gates,which can provide a reference to the other similar projects.
