摘要
基于推流公式法对闸门流量系数进行率定,采用逐步图解法求解得到闸门出流公式,并对该公式进行检验和误差分析,最终绘制出流量工作曲线,为秦淮新河闸门日常调度和运行提供指导依据。
Based on the push flow formula method,the flow coefficient of the sluice was calibrated.Using the step-by-step graphic method,the outflow formula of the sluice was gotten,the error of the formula were tested and analyzed,and finally the flow working curve was drawn,which provided guidance for the daily dispatching and operation of the sluice.
