分析了综合式消力池在消力坎计算中存在的问题,提出了计算消力坎高度和消力池深度总高度的估算方法。根据文献[6-7]对波状床面水跃共轭水深和水跃长度的研究成果以及综合式消力池的一般计算方法,给出了波状床面综合式消力池跃前水深的显式计算公式、跃后水深的迭代计算公式。在文献[11]对消力坎淹没系数研究的基础上,对于淹没度,在0.45≤h_s/H_(10)≤0.92范围内重新给出了精度更高的计算淹没系数的公式。通过算例给出了波状床面综合式消力池的水力计算过程和计算步骤,推荐在综合式消力池的水力计算中,先假设消力池的深度,再计算消力坎高度的简单计算方法。通过对比分析可以看出,波状床面综合式消力池与普通综合式消力池相比较,可以大幅度地减小消力池深度、消力坎高度、跃后水深和消力池长度,提高了消能效果,是一种值得推荐和研究的消力池形式。
The problems existing in the calculation of the dike are analyzed, and the method of calculating the height of the dike and the total height of the digester is proposed. According to the research results of the conjugate water depth and the hydrofacies length of the wavy bed in literatures [6-7], and the general calculation method of the composite stilling basin, Formula, jump after the depth of the iterative formula. Based on the study of [9] and [11] on the inundation coefficient of stress kananas, the formula for calculating the inundation coefficient is given again with higher accuracy for the inundation degree in the range of 0.45≤h_s / H_ (10) ≤0.92. Through the example, the hydraulic calculation process and the calculation steps of the corrugated bed comprehensive sinking basin are given. It is recommended that in the hydraulic calculation of the integrated sinking basin, the depth of the sinking basin should be assumed first, Calculation method. Through comparative analysis, it can be seen that the corrugated bed integrated descending pool can greatly reduce the depth of the stilling pool, the height of the descending ridge, the water depth after the jump and the length of the stilling pool, compared with the general integrated descending pool, Improve the energy dissipation effect, it is worth recommending and research of the stilling pool form.
