| 摘 要： | 使用TK-2D软件建立了基于不规则三角形网格的葫芦岛海域的潮流场和悬沙场数学模型,根据现场实测资料对模型进行了充分的验证,对葫芦岛海域的潮流泥沙场进行了数值模拟,根据模拟计算结果,对该海域的潮流场和泥沙场特征进行了分析。研究结果表明:(1)葫芦岛海域海区的潮流运动为半日潮流类型;(2)该海区的潮流运动基本为平行岸线的往复运动;(3)该海区的潮流动力中等;(4)正常天气条件下水体含沙量很小,且分布均匀。

| Abstract: | Based on TK-2D software,mathematical models with irregular triangular grid of tidal current and suspended sediment in Huludao sea area are set up.Verification and validation are carried out fully against field measured data,and then tidal current field and suspended sediment field are numerically simulated.According to the simulation results,analyses are made on the characteristics of tidal current field and suspended sediment field.The study results show that:(1) tidal current in this sea area is of semi-diurnal type.(2) tidal current in this sea area assumes basically alternating current parallel to shoreline.(3) tidal force in this sea area is moderate.(4) The sediment content in water is very little generally and is evenly distributed. |
