摘　　要：以琼州海峡白沙浅滩海上人工岛工程为研究对象,在实测资料分析的基础上,基于非结构网格建立潮流数值模型,分析了工程前后的流场动力变化特征,同时采用悬沙模型和底沙模型预测工程实施后工程海域的地形演变特征,研究了如意岛工程对周边海域的动力变化影响,对工程海域泥沙冲淤进行了分析和预测。Taking the offshore artificial island project of Qiongzhou Strait’s white sand shoal as the research object,on the basis of the analysis of the measured data,we establish the tidal current numerical model based on unstructured grid,and analyze the dynamic variation characteristics of the flow field before and after the engineering.Using the model of suspended load and the model of the bottom sand,we predict the characteristics of the terrain evolution after implementation of the engineering,research the impact of dynamic changes in the water surrounding of Ruyi island project,and forecast the sediment scouring of the engineering sea area.
