摘要
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 question existed on ridge height of comprehensive stilling basin is analyzed and then the estimation methods of the height which is equal to the sum of the ridge height and the depth of stilling basin are put forward. According to the results about conjugate depth and length of jump occurring on corrugated beds of literature[6-7] and the general calculation method of comprehensive stilling basin, the explicit formula of initial depth of jump and iterative formulas of sequent depth is put forward of comprehensive stilling basin with corrugated beds, respectively. And the calculation formula with much higher precision of submerged coefficient of baffle wall style is proposed under 0.45≤hs/H（10）≤0.92 based on result of literature[11]. The hydraulic calculation procedure of factors of the comprehensive stilling basin is shown, and it is much simpler to solving ridge height with the depth of stilling basin is assuming first. It is indicated that comprehensive stilling basin with corrugated beds is well worth recommending and studying which is playing a significant role in decreasing depth of stilling basin, ridge height, sequent depth and length of jump of stilling basin compared to general comprehensive stilling basin.
