摘要
利用现行《水闸设计规范》推荐的两个泄量计算公式对11座低落差、高淹没大中型水闸泄量进行计算,两者相差10%左右,与相应试验结果相比较,第一公式计算值偏大,第二公式计算值偏小,但前者相对误差显著小于后者.两者均值较试验值大,但相对误差小.建议采用第一公式计算值或第一、第二公式计算均值作为规划设计计算流量,并用试验与之复核.对第二公式中综合流量系数μ0的影响因素进行了探讨,根据模型实测资料,绘出了μ0试验曲线和推荐值.
The discharges of 11 large and middle scale sluice of low water level difference and high submergence degree are calculated by using the two formula of present design specification for sluice. It is shown that comparing with experimental result, the computing values by using the first formula are larger, the computing values by using second formula are smaller, but the former relative errors are remarkably smaller than the latter. It is suggested that the first formula computing values or the computing average values by using the two formulas are used as design discharging in the hydraulic design period, which should be checked by hydraulic model experiments. According to the experimental data, the suggested curve and values are presented here.
