摘要
针对密云水库调蓄工程中节制闸无具体过流公式及控制运用图表的问题,运用量纲分析法拟定李史山泵站节制闸过流公式并绘制过流曲线。结果表明,基于量纲分析法推导的平板闸门过流公式简单、精度较高,相对误差均在±7%以内,平均误差为3.2%,可较为准确计算过闸流量;应用过流公式绘制的过流曲线简洁、直观,可为工作人员操作闸门提供指导参考。
In view of the problem that there is no specific overflow equation or controlling application chart for check-gate in Miyun Reservoir Regulation and Storage Project,this paper uses the dimensional analysis method to propose the overflow equation and draw the overflow curve check-gate for the pumping station of Li Shishan.The results show that the overflow equation which is derived based on the dimensional analysis method is simple and highly accurate.The relative error is within±7%,and the average error is 3.2%,which can accurately calculate the overflow discharge;The overflow curve drawn by the overflow equation is concise and direct,which can provide guidance and reference for the staff to operate the gate.
