| 摘 要： | 横沙东滩是横沙岛东侧的大型水下浅滩,与崇明东滩、九段沙同为长江河口拦门沙地区的3大浅滩之一;长期以来位置和海床均十分稳定,是建设挖入式港池的理想区域。利用三维潮流泥沙数学模型从水动力、泥沙输运角度对长江口横沙浅滩建设挖入式港池方案进行数值模拟研究,分析了工程前后潮流泥沙变化,为横沙东滩建港及影响分析提供科学依据。

| Abstract: | Hengsha east shoal is a large underwater bank located at the east side of Hengsha island.Hengsha east shoal,together with Chongming eastern shoal and Jiuduan shoal are three largest shoals in the Yangtze mouth-bar area.The Hengsha east shoal is an ideal area for port construction because of its stable location and seabed form.A 3-D tidal-sediment model is used to simulate the current dynamics and sediment transport with a dig-in harbor basin built at the Hengsha east shoal.The changes of tidal current and sediment flux before and after the project are compared to analyze the impact of port-building. |
