摘要
闸门流量系数的准确率定是流量计算及水资源调度的重要依据.通过对湛江与茂名交界处的高岭拦河闸采用走航式ADCP法进行水文测验,获得水位流量数据,分析闸门流量系数、闸门相对开度、闸门开度与流量关系.结果表明:闸门相对开度与流量的关系、闸门开度与流量的关系,相关系数均达到了 0.97以上,其中闸门开度与流量的关系,相关系数达到了 0.99以上,且用该方案推流更为直观,所以实际应用中建议采用闸门开度与流量关系进行推流.
Abstract
The accuract calibration of gate flow coefficient is an important basis for flow calculation and water resource scheduling.By using the navigational ADCP method,the water level and discharge data of Gaoling sluice at the junction of Zhanjiang and Maoming are obtained,and the coefficient of gate discharge,the relative opening of gate and the relationship between gate opening and discharge are analyzed.The results show that the correlation coefficient between the relative opening of the gate and the flow rate and the relationship between the opening of the gate and the flow rate is above 0.97,and the correlation coefficient between the opening of the gate and the flow rate is above 0.99,and the scheme is more intuitive to push the flow,so it is recommended to use the relationship between the opening of the gate and the flow rate to push the flow.
