为了研究上海国际航运中心洋山深水港区四期工程导流堤工程对周边海域流场的影响,采用MIKE21里面的HD模块构建杭州湾及长江口海域整体潮流数值模型,分别对导流堤建成前后附近海域流场进行数值模拟,分析导流堤建成后工程附近海域流场特征。研究表明:导流堤建成后,四期码头前沿较大范围的回流区和缓流区基本消失,导流堤和四期码头前沿海流流向基本与码头走向保持一致,流速有所增大,导流堤的建设使码头前沿海流得到很好的改善,起到了归顺潮流的作用,有利于码头前沿水深的维持及船舶靠离港的安全。
In order to study the impact of the diversion dike project of the fourth phase of Shanghai International Shipping Center Yangshan Deepwater Port on the flow field around the sea, the numerical model of overall flow in the Hangzhou Bay and the Changjiang Estuary was constructed by using the HD module in MIKE21. Before and after the sea near the flow field numerical simulation to analyze the flow field around the dam after the completion of the project characteristics. The results show that after the completion of the diversion embankment, the large area of the recirculation zone and the slow flow area in the front of the fourth phase basically disappears. The flow direction of the frontal flow along the diversion bank and the fourth phase of the pier remains basically the same with the increase of the flow rate, The embankment construction has greatly improved the frontal current of the wharf and has played a role of leading the tidal current, which is conducive to the maintenance of the water depth at the front of the wharf and the safety of the vessels leaving the port.
