摘要

酉酬水电站坝址河谷狭窄、岸坡陡峻,河道平直,洪水峰高量大,下游消能防冲问题较为突出.通过水力学计算和模型试验对比分析,证明该工程采用的宽尾墩+底流消能方案具有消能率高、尾水稳的特点,很好的解决了酉酬水电站"大单宽流量、低弗劳德数"水流消能的难题.
        There is narrow valley,steep slope and flat and straight channel in the dam site of Youchou Hydropower Station.And the flood peak is high and the discharge is large.The energy dissipation problem of the downstream of the station is remarkable.By the comparative analysis of hydraulic calculations and model test,the results show that the plan of flaring pier +underflow energy dissipation had the feathers of high energy dissipation rate and stable tail water which is a good solution to the energy dissipation problem of big unit discharge and low Froude number.
