黄沙洋水道末梢浅水槽建港工程潮流数值模拟与泥沙淤积计算

Tidal current numerical simulation and sediment deposition calculation of port construction in shallow water tank at the end of Huangshayang channel

为研究有关潮汐通道浅水槽建港问题,以辐射沙脊群黄沙洋水道末端的条渔港为例,首先,进行了自然条件分析;其次,构建二维水动力数学模型,根据实测资料对水动力模型进行验证,并对工程前后整体海区的潮流流态、特征点横流大小进行了分析;最后,应用泥沙经验公式计算条渔港区港池及航道的年回淤量。以上数据可为港区方案设计提供科学依据。

Taking Tiaoyugang as a case study,the port,which locates at the end of the Huangshayang channel’s of radial sandridges,is being built in shallow tank of tidal channel.First of all,the natural conditions are analysed.Then,based on the calibration of two-dimensional hydrodynamic mathematical model,the results act in accord with the measured data.The tide current field of whole computational region and the characteristic point’s cross flow on before and after the project are discussed.Finally,using the sediment experience formula calculates the yearly deposition quantity in the harbor basin and channel.The conclusion can provide the scientific basis for the port design.
