摘　　要：综合多次现场实测资料,分析了盘锦港10万吨级深水航道的水沙特征,讨论航道回淤泥沙来源和产生泥沙骤淤的可能性。研究结果表明:1)该海区波浪动力不强,以风浪为主;潮汐为非正规半日潮,属中强潮海域;潮流为正规半日潮流,主要以往复形式运动,口门内侧存在强度较弱的旋转流。2)河口区和近岸浅滩含沙量高、外海深水区含沙量较低,泥沙主要以悬浮形式运动,大风影响下各站含沙量均显著大于常规天。3)航道沿程底质泥沙呈粗细交错分布;波流作用下两侧岸滩就地起动搬运的泥沙为航道淤积的主要来源和直接来源,回淤物质较细,泥沙淤积以悬沙落淤为主;出现骤淤碍航的可能性较小。Based on the field data,the characteristics of hydrodynamic and sediment along the 100,000 DWT deep water channel of Panjin Port are analyzed,and the sediment source of channel siltation and the possibility of sudden siltation are also discussed.The main research conclusions are shown as follows:1)The wave in this area is not strong,mainly wind wave;the tide is irregular semi-diurnal tide,which belongs to the middle strong tide area.The current is regular semi-diurnal tidal current,which mainly moves in the form of rectilinear current,and there is weak rotary current in the inner side of the entrance.2)The sediment concentration in estuarine area and near shore shoal is high,while that in open sea deep water area is low.The sediment mainly moves in the form of suspension.The sediment concentration in windy days is significantly higher than that in normal days.3)The distributions of sediment grain sizes along the channel are coarse and fine alternately;under the action of wave and current,the sediment incipience and transport in shoals on both sides of the channel are the main source and direct source of channel siltation;the siltation sediment in channel is relatively fine,which means that the siltation is mainly suspended sediment deposition;the possibility of sudden siltation is relatively small.
