| 摘 要： | 二河闸节制闸作为洪泽湖洪水出流的主要水利工程,在其控制运行中多次出现淹没式堰流流态,推求该水情条件下的流量一直采用的是连实测流量过程线法。为了能够更合理地掌握水工建筑物的出流规律,从而使流量推求更加精确,根据二河闸淹没式堰流流态下的历年实测流量资料,对其测验数据进行分析并率定出二河闸丰水期淹没式堰流的水位流量关系曲线。

| Abstract: | In control operation of the Erhe Sluice(the main outlet of the Hongze River),submerged overflow repeatedly appeared and the observed discharge hydrograph method was frequently used for the flow calculation.By analyzing the observed discharge data and calibrating the rating curve of submerged overflow of the Erhe Sluice in high water period,we can control hydraulic structure regulation more reasonably and make the flow calculation more accurate. |
