胶州湾前湾围填海工程对其污染物输运影响的模拟研究

采用ECOMSED和“干、湿”点法构建了胶州湾潮流的三维动边界数值模型。模型验证良好，可以较好地模拟胶州湾潮流场。利用所建模型模拟了前湾填海工程前后胶州湾潮流场。基于Lagrangian粒子追踪法，采用单个粒子及粒子群模拟了前湾填海工程前后胶州湾污染物输运。对比工程前后污染物运动轨迹，分析了工程对胶州湾污染物输运的影响规律及范围。在此基础上，对胶州湾排污口的布置给出了参考建议。

Numerical study on the influence of the forebay reclamation on pollutant transport in the Jiaozhou bay

A 3D numerical model of Jiaozhou bay tide current was established based on ECOMSED model.In the model, the dynamic boundaries was dealed with dry-wet point method.The verification of the model showed that it could predict the tidal current well in the Jiaozhou bay.The model was then used to simulate the tidal current before and after the forebay reclamation in the Jiaozhou bay.Based on the Lagrangian particle tracking method, the pollutant transports before and after the forebay reclamation in the Jiaozhou bay were simulated by tracking the movement of single particle and particle swarm.By comparing with the trajectories of pollutant before and after the reclamation, the influence rules and scope of the forebay reclamation on pollutant transport in the Jiaozhou bay were analyzed, and some suggestions for the arrangement of sewage outlet in the Jiaozhou bay area were provided based on these.
