摘　　要：根据2013年、2017年和2019年宝应抽水站抗旱运行期间实测的三阳河输水流量资料,针对宜陵闸不同的控制工况分别进行了水位流量关系分析。结果表明:江都东闸下游与宜陵闸上游水位差和三阳河输水流量具有较好的相应性,水位流量点据定线精度均达到三类精度以上。对三阳河输水流量的定量分析,可为宝应抽水站在设计工况下高效安全运行提供技术参考,对抽引江水北送、充分发挥泵站经济社会效益具有现实意义。According to the measured water flow data of the Sanyang River during the drought resistant operation of the Baoying Pumping Station in 2013,2017 and 2019,the stage-discharge relationship were analyzed for different control conditions of the Yiling Gate.The results showed that the water level difference between the lower reaches of Jiangdu east sluice gate and the upper reaches of Yiling sluice gate had a good correspondence with the water flow of Sanyang River,and the accuracy of the water level and flow points according to the alignment was more than three types of accuracy.The quantitative analysis of the flow rate of Sanyang River could provide a technical reference for the efficient and safe operation of Baoying pumping station under the design condition,and it's of practical significance for the pumping station to pump water from the Yangtze River to the north and give full play to the economic and social benefits.
