  1. Based on experimental result of energy dissipation and scour protection for downstream of spillway at yu jian kou power station, this paper discusses the flow characteristics, aerated characteristics of flaring gate pier for low dam pivot, the influence on pressure of dam surface and the result of energy dissipation for flaring gate pier. it is put forward to be an available method to solve the problems of energy dissipation and scour protection for depth of covering strata, poor geologic condition and weakness of resistance to scour capability under reasonable use of flaring gate piers and auxiliary dissipaters. thus, a new method is obtained for release of floodwater and energy dissipation of low dam pivot which are provided with low water head, great unit discharge and low froud coefficient. it may be used for reference for design and test workers

    結合魚劍口電站壩下消能防沖試驗研究成果，對低壩樞紐寬尾墩的水流特點、摻氣特性、寬尾墩對大壩泄流能力和壩面壓力的影響以及寬尾墩的消能效果等問題進行了初步探討，提出了合理地使用寬尾墩結合輔助消能設施可有效地解決壩下覆蓋層深，地質條件差，抗沖能力弱的低壩樞紐的消能防沖問題，從而為具有低水頭，大單寬流量，低佛氏數特點的低壩樞紐泄洪消能開辟了一條新途徑，可供有關低壩樞紐設計與試驗工作者借鑒與參考
