摘要
迷宫堰与直线堰相比,在相同堰上水头条件下,可大幅度提高过流能力。从因次分析的角度阐述了迷宫堰流量系数的影响因素,并在分析讨论了前人的几种迷宫堰流量系数计算方法的基础上,拟合出迷宫堰流量系数计算公式,可为实际工程应用提供方便。
Compared with beeline weir, labyrinth weir can provide larger flow capacity with the same water head above the weir. The influencing factors of the discharge coefficient of labyrinth weir are expatiated from the aspect of dimensional analysis, and the calculation formulae for the discharge coefficient of labyrinth weir are fitted on the basis of summary of several calculation methods of discharge coefficient of labyrinth weir of other scholars. The research can provide convenient ways of calculation for the actual uses.
