摘　　要：如东洋口港区北水道拟建15万t级航道工程。由于工程区域位于潮波系统交汇区,潮流场呈辐射状、水沙情况复杂,为给15万t级航道工程提供稳定性依据,基于实测水文、地形资料,先建立东中国海潮波数学模型,再将工程海域水文泥沙条件代入,建立三维潮流泥沙数学模型对工程区域水沙特性进行了模拟计算、分析。分析结果显示:工程海域的潮流属规则半日潮流,明显呈驻波性质;工程后航道内最大淤积强度为0.9 m/a,平均淤积强度为0.6 m/a左右,年淤积总量为415.2万m^3,淤积强度较大。建议在主航槽两岸设置挡沙堤,对主航道进行必要的掩护。The north waterway of RuDong YangKou port area is planned to open a 150 thousand tons channel.Because the project is located in the intersection area of tidal wave system which has tidal current fields,complex water sand.In order to provide stability basis for 150 thousand tons waterway project,east China tidal wave mathematical model is established based on the measured data of hydrology and topography,then the three-dimensional tidal current and sediment mathematical model is established considering the engineering sea hydrological and sediment conditions in order to simulate the water sediment characteristics in that area.The analysis results show that:(1)the tidal current in the area is a regular half-day tidal current,which is stationary;(2)the maximum siltation intensity in the channel after the project is 0.9 m/a,the average siltation intensity is about 0.6 m/a,the annual total volume of siltation is 415.2×10^4 m^3,and the siltation intensity is large.It is suggested to setup sand barriers on both sides of the main channel to provide necessary cover for the main channel.
