摘要
对崆峒水库输水洞平板闸门改建为锥形阀后的消力池进行了模型试验研究。锥形阀消力池内流态稳定,池末端水流没有直冲消力坎且没有明显的水面跌落,消能效果较好。试验结果分析表明:当流量不同时,消力池的最优体型亦有所不同。
After the Kongdong reservoir water hole plate gate rebuild into a cone valve, the stilling basin, model test was conducted. The flow in stilling pool was stable, no turbulent flow rush to the floor sill at the stilling pool terminal and there was no obvious water drop, energy dissipation effect was good. The results show that when the flow is different at the same time, stilling basin optimal size is also different.
