| 摘 要： | 索风营电站采用了宽尾墩 阶梯溢流坝的坝面泄流形式，这种坝面泄流形式由我国首创，虽在实际工程中有所应用，但缺少3维数值计算成果．紊流数值模拟计算了在设计水位条件下的掺气情况、压力分布、紊动动能和紊动耗散率等水力特性，表明宽尾墩 阶梯溢流坝的坝面泄流形式使高水头大单宽泄流有了突破性的进展．数值计算时单宽过量已达141m^3／s．m．

| Abstract: | Suofengying hydro-power station adopts the stepped spillway with flaring gate pier, a new-style dam of discharge, pioneering in China. It has been used in practical projects, but it is short of 3D computer calculating. The turbulent numerical simulation calculates some hydraulic characteristics such as aeration, pressure distribution, the turbulent kinetic energy and dissipation rate under the conditions of design water level. The calculated results indicate that the discharge style of stepped spillway with flaring gate pier has made a great breakthrough in the dam with high hydraulic head and big flows. The calculating discharge per unit width is 141m3/m.s. |
