| 摘 要： | 本文通过试验分析,对具有驼峰堰的泄水闸下游平底消力池中的淹没水跃特性进行了研究。认为:当淹没水跃的跃前佛氏数F_(?)=3.4～7.3、淹没系数S<0.7时,消力池及其下游的流态不会因水跃被淹没而恶化,淹没水跃的消能效果优于自由水跃。

| Abstract: | This paper presented a viewpoint, i. e. As for the submerged hydraulic jump in the sluice weir downstream, when the supercritical Froude Number is from 3.4 to 7.3 and the Coefficient of submerged' is less than 0.7, the flow condition in stilling basins and it downstreams will not worsen,due to the free jump becomes submerged,and the energy dissipation effect of the submerged hydraulic jump is better than that of the free hydraulic jump. |
