ECOMSED三维悬沙扩散数值模型在凤城港航道清淤工程建设中的应用

ECOMSED Math Model and Its Application in Fengcheng Ports Construction

文章用ECOMSED三维近岸水动力泥沙数学模型对山东烟台凤城港附近海区的潮流场进行了较高分辨率数值模拟,在此基础上进一步建立了凤城港航道清淤工程过程中三维悬沙输运-扩散数学模型。该模型以航道中心为悬沙线源,根据工程过程中连续开挖的特点较好的引入泥沙输入源强,准确地模拟了该航道中连续开挖36小时,工程区域及其周围海域表、中和底层泥沙浓度分布特征及其随时间的变化规律。

In this paper,ECOMSED math model is applied into high-resolution numerical simulations of flow field in sea area around Fengcheng ports.Asediment transportation math model for dredged sediment along ports routine is established based on the above.Then located the sediment sources along the ports construction routine,which was at the center of the ports grids,this model enabled us to more accurate simulate distribution characters of construction area and the surrounding area table,middle,bottom sediment concentration and its variation with time when the channel was given 36 hours of continuous excavation.
