| 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：当淹没水跃的前佛氏数Ｆｒ１＝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库。

| Abstract: | For submerged hydraulic jump on the downstream side of sluice weir, when the supercritical Froude number is from 3. 4 to 7. 3 and the submergence coefficient is less than 0. 7, the flow condition in stilling basin and its downstream area will not worsen even the free jump becomes submerged. The energy dissipation effect of the submerged hydraulic jump is better than that of the free hydraulic jump. |
