  5. Abstract : 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
