摘　　要：为解决淮河临淮岗工程深孔闸过闸流量计算问题,本文探讨分析了闸孔过流特征,通过与实测数据对比,检验了经验公式、模型试验推荐公式用于过闸流量计算的适用范围。对实测综合流量系数与推荐综合流量系数的数据进行内插,采用二阶多项式进行曲线拟合,推算出流量系数与相对开度的函数关系。通过实测数据与拟合公式计算结果比较,验证了计算方法具有一定的准确性,适用于各相对开度条件下闸孔流量的监控,可初步解决过闸流量计算问题,为水闸精准调度提供了依据。To address the issue of calculating the flow rate through the deep-hole gates in the Linhuaigang Project on the Huaihe River,this paper explores and analyzes the flow characteristics through the gate holes.By comparing with measured data,the applicability range of empirical formulas and model experiment recommended formulas for calculating the flow rate is examined.Data interpolation between the measured comprehensive flow coefficient and the recommended comprehensive flow coefficient is conducted,and a second-order polynomial is used for curve fitting to deduce the functional relationship between the flow coefficient and the relative opening.The comparison between the actual data and the results calculated using the fitting formula verifies the accuracy of the calculation method.It is suitable for monitoring the gate hole flow under various relative opening conditions and can preliminarily solve the flow rate calculation issue,providing a basis for precise regulation of water gates.
