摘　　要：针对长江下游感潮河段水闸引排水调度的精细化需求,以新孟河界牌水利枢纽为研究对象,构建潮位预报与引排水流量计算模型。采用多元线性回归分析潮汐特性,结合镇江站与新孟河闸的水位实测资料,建立镇江站潮位动态预报方案。在此基础上,推求新孟河闸的过程水位,并构建闸下水位与引排水流量的函数关系,实现潮周期内引排水流量的精细化计算以满足水利枢纽调度需求。研究成果可为长江下游感潮河段水闸引排水调度提供理论方法和技术支撑。Aiming at the refined demand of diversion and drainage operation of sluices in tidal reach of the lower reaches of the Yangtze River,taking Jiepai Water Control Project of Xinmeng River as a research object,a model of tide level forecast and diversion and drainage flow calculation is established.Using multiple linear regression analysis of tidal characteristics,combined with water level measurement data from Zhenjiang Station and Xinmeng River Sluice,a dynamic tidal level forecasting scheme for Zhenjiang Station is established.On this basis,the process water level of the Xinmeng River Sluice is calculated,and a functional relationship between the water level under the sluice and the drainage flow is constructed to achieve precise calculation of drainage flow during the tidal cycle to meet the dispatching requirements of the water conservancy hub.The research results can provide theoretical method and technical support for sluice diversion and drainage operation in tidal reach of the lower reaches of the Yangtze River.
