| 摘 要： | 以连云港旗台防波堤为研究背景,基于非结构网格有限体积法建立二维潮流泥沙数学模型,研究旗台防波堤建成前后港区附近潮汐、潮流与悬移质含沙量的变化,以期为日后连云港港口开发建设提供技术支持。研究认为,旗台防波堤的建设完成后,港区内外潮汐特性基本不变;港区内潮流呈减弱趋势,防波堤口门处潮流增强,防波堤内侧港区形成明显的回流区域;港区外侧高含沙量水体向外海移动,港区内最大含沙量整体降低。

| Abstract: | The 2D tidal current and sediment mathematical model is built with FVM to Qitai breakwater in Lianyungang to study the changing of tide,tidal current and suspend sediment concentration nearby the port after completion of the breakwater,so as to provide technical support for future development of Lianyungang port.Accompanying the completion of Qitai breakwater,the nature of tide is altered neighboring the port and the tidal current is weakened in the harbor district but strengthened in the breakwater gap,the water with high suspend sediment concentration is away from the breakwater and the maximum sediment concentration in the harbor district is reduced. |
