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。
In order to understand the hydro-jumping characteristics and relative parameters of the slope-diverting dissipation basin, the energy-dissipating effect of the slope-diverting dissipation basin was evaluated. The water jump of the collapse-sinking basin was studied by the model test, and the formula of conjugate depth was proposed. Length, conjugate water depth ratio, energy dissipation and other related hydraulic parameters and their variation. The results show that under the experimental conditions, the error between the calculated results and the measured values is smaller and the accuracy is higher. The ratio of water jump length to the conjugate water depth and the Froude number all follow the positive proportional rule. The number is proportional.
