针对大连湾人工岛的建设预案,在人工岛多种长度及宽度的组合条件下,运用MIKE21flowmodel模块进行人工岛建设前、后的海湾流场模拟,在纳潮差的概念下,探讨研究嵌入人工岛后海湾水体交换的变化规律,进而评价人工岛对海湾水环境的影响。在不同的人工岛功能定位前提下,综合考虑人工岛和水体交换的诸多因素,分别给出了可供规划参考的人工岛推荐方案。
Based on the plan to build an artificial island in Dalian bay, under a variety of artificial islands in the combination of length and width conditions, and using MIKE21 flow model, we simulate the gulf flow field before and after the construction of the artificial island. Under the concept of the tidal level gap, we study the water exchange, pollutant dispersion and retention rate in the gulf, and evaluate the impact of the artificial island on the water environment in the gulf. Under different functional premises of the artificial island, and considering many factors of the artificial island and water environment, we put forward the recommendation for the artificial island.
