摘要
人工岛作为人工建造的海洋工程结构物,其嵌入必然对其附近水域的水动力特征造成影响。针对不同的人工岛建设预案,基于ECOMSED建立了大连湾海域的三维潮流模型,通过拉格朗日粒子追踪技术,采用单个粒子和粒子群模拟了大连湾水域污染物输运过程。对比分析了人工岛嵌入前后粒子运动的三维运动规律,最后从污染物扩散的角度为人工岛的规划以及排污口的布置给出推荐方案。
As man-made ocean engineering structures, artificial island inevitably affects the hydrodynamic characteristics of the gulf. Based on ECOMSED, a 3-D tidal-flow numerical model of Dalian bay was established for the arranged schemes of artificial island. According to the Lagrangian particle tracking technology, the movements of single particle and particles swarm in the gulf were simulated. By analyzing the 3D movement of particles before and after construction of artificial island, the recommended planning of artificial islands and the arrangement of drain outlet were proposed based on pollutant movement.
