摘要
根据长江南京江段的水流特性,采用Delft-3D数学模型,对长江南京江段滩群演变及其分流特性进行分析计算研究。结果表明,新生洲汊道的演变对下游新济洲汊道、新潜洲汊道、梅子洲汊道和八卦洲汊道的演变有明显影响,在现状江道条件下,若新生洲左汊未来发展,将会引起下游新济洲左汊衰退、新潜洲左汊衰退、梅子洲左汊发展和八卦洲左汊衰退,这样为全面地规划整治长江南京江段的工作提供科学建议。
Based on the water flow characteristics of Yangtze River in Nanjing,researches on the shoal group evolution in the area and its flow-dividing characteristic were made by adopting Delft-3D mathematical model.According to the results,the riverbed evolution of Xinshengzhou had obvious influence on the flow-dividing characteristics at Xinjizhou,Xinqianzhou,Meizizhou and Baguazhou branched channel on downstream reach,in the current channel situation,if Xinshengzhou＇s left branch is developed,it will lead to series of problems,such as decline of some branches.It offered some advice for the programming and regulation of the reach of Yangtze River in Nanjing.
