天津港大港港区口门布置优化水流条件

Flow condition for optimizing entrance layout of Dagang harbor of Tianjin Port

建立平面二维潮流数学模型，针对天津港大港港区口门防波堤不同长度及布置形式，从通航水流条件对不同口门布置方案进行计算分析。兼顾目前规划条件和未来发展条件，拟推荐防波堤长度4~5 km，口门内设置净宽1000 m的横堤，且横堤位置尽量靠近口门。研究成果可作为港区口门优化设计的依据及管理决策的参考。

By establishing a two-dimensional tidal current mathematical model for Dagang Harbor of Tianjin Port, the break-water at the entrance of different length and layout, we calculated and analyzed the different layout schemes of the entrance from the navigation flow conditions. Both planning condition and future development condition, the recommend breakwater length is 4 km to 5 km, setting the bankhead at the entrance of 1 000 m width, and the position should be as close as possible to the en-trance. The results can be used as the scientific evidence for optimization design of the entrance of Dagang Harbor.
