基于不规则三角形网格有限差分法建立了江苏如东海域大范围和小范围嵌套二维潮流数学模型,在对模型验证的基础上,对西太阳沙2 km2人工岛工程及配套码头工程方案的潮流场进行了数值模拟研究。根据模拟结果,就人工岛及配套码头工程对周围海区的潮流场、各水道潮量的影响进行了分析,从潮流动力角度论证了工程的可行性。

2-D tidal flow nested mathematical models of coastal waters at Rudong,Jiangsu Province,are set up,which include a larger domain model and a smaller domain model inside the larger domain.The models are based on irregular triangular grid and the finite difference scheme.On the basis of model verification against field measured data,numerical modeling of tidal flow is carried out for the 2 km~2 artificial island and the associated wharf project on Xitaiyangsha shoal.According to the calculation results,the effects of the project on tidal flow field and on the tidal discharge of various waterways are analyzed.The feasibility of the 2 km~2 artificial island and the associated wharf project is demonstrated from the view point of tidal force.
