| 摘 要： | 根据连云港海域的特点,建立能考虑风浪影响的三维潮流、泥沙数学模型,对真实的"韦帕"台风作用下的潮流场和泥沙场进行模拟,力求更合理地反映近岸泥沙运动规律。数学模型计算得到的流场、含沙量场和航道回淤结果与现场实测资料进行验证,二者吻合较好。在此基础上,对连云港港30万吨级航道在"韦帕"台风作用下的回淤情况进行了预测,给出了航道的沿程淤强分布,为航道的设计提供依据。

| Abstract: | A 3D tidal current and sediment mathematical model under the effect of wind and wave is set up and used to simulate the current field and sediment concentration field under typhoon"WIPHA"around Lianyungang sea area.The computed results and the field measured data are compared and verified.The verification shows that the simulated result tallies well with the field observation data.On this basis,the mathematical model is used to simulate the sediment deposition of 300 000 DWT deep-water channel of Lianyungang port during"WIPHA"typhoon.The deposition thickness of the channel is presented,which can provide a basis for the design of the navigation channel. |
