| 摘 要： | 为了解折坡扩散消力池的水跃特性及相关参数、判别其消能效果,通过模型试验的方法对折坡扩散消力池水跃进行了研究,提出了共轭水深计算公式,分析了水跃长度、共轭水深比、消能率等相关水力参数及其变化规律。结果表明,在试验条件下,公式计算结果与实测值相比误差较小,精度较高;水跃长度与共轭水深比、佛劳德数均遵循正比例变化规律;水跃消能率与佛劳德数呈正比。

| Abstract: | To know water characteristics of hydraulic jump and related parameters for judging the effect of energy dissipation in stilling basin with upstream expansive slope, this kind of stilling basin was studied based on hydraulic model test. The calculation formula of conjugate water depth was put forward. The conjugate depth, length of hydraulic jump, dissipation rate and other related hydraulic parameters were analyzed. Compared with the measured values in the test conditions, it shows that the average relative error of the formula was small, and the formula has high accuracy; the length of hydraulic jump has positive interconnection with conjugate depth ratio and Froude number, and dissipation rate has positive interconnection with Froude number. |
