摘要
以天津港新港航道(口门内)工程为例,建立了工程海域的三维潮流数学模型,在模型验证的基础上研究了航道流场的分布和变化情况。研究结果表明:工程海域的潮流分布特征为外海水域流速较大,近岸及主港区水域流速较小,涨潮流速大于落潮流速,疏浚后流态与现状相似。研究成果可为本航道工程设计提供参考。
A three-dimensional tidal current numerical model of the engineering sea area was established,using Xingang Channel(inside the port entrance)project of Tianjin Port as a case study.Based on the validation of the model,the distribution and variation of the flow field in the channel were analyzed.The research results indicate that the tidal current distribution in the engineering sea area is characterized by higher flow velocities in offshore waters and lower velocities in nearshore and main port areas,with flood tide velocities exceeding ebb tide velocities.After dredging,the flow patterns remain similar to the current conditions.These findings provide a reference for the design of this channel engineering project.
