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。
Using the ECOMSED and “dry, wet ” point method to build a three-dimensional dynamic boundary numerical model of the Jiaozhou Bay tidal current. Model validation is good, can better simulate the Jiaozhou Bay tidal current field. The model was used to simulate the tidal flow field of Jiaozhou Bay before and after the reclamation project of Qianwan Bay. Based on Lagrangian particle tracing method, single particle and particle swarm were used to simulate the pollutant transport in Jiaozhou Bay before and after the reclamation project of Qianwan. Contrasting the trajectories of pollutants before and after the project, the impact of the project on the pollutant transport in Jiaozhou Bay was analyzed. Based on this, the paper gives some suggestions for the layout of the sewage outfall in Jiaozhou Bay.
