| 摘 要： | 通过ＧＨＡＺＩ－ＢＡＲＯＴＨＡ水电工程尾部节制闸水工模型试验，获得了过闸流量－开度－尾水位水流特性曲线。分析比较了理论计算与试验实测过闸流量，对过闸流量与尾水位作了相关分析，经试验数据回归分析计算，提出了计算闸孔淹没出流时淹没系数的经验算式，改进了传统采用查图表获得淹没系统的不便方法，为尾部节制闸调控系统控制闸门开度提供了科学依据。

| Abstract: | The flow characteristic curve of the tail regulator gate of GHAZI BAROTHA hydropower project has been obtained by hydraulic model test. The discharge by theoretical calculation and the discharge by model test measurement are analyzed and compared. Experiemtal equation of the submergence coefficient of submerged orifice flow is presented by regression analysis of the test data. The traditional method of getting submergence coefficient by graphic chart is improved. It provides scientific basis for future operation of the tail regulator control system. |
