摘　　要：伶仃洋是华南具有重要航运功能的河口湾,在其东西两岸分布着广州港南沙港区、深圳港西部港区、中山港等重要港口,伶仃航道和铜鼓航道是广州港和深圳港的重要出海通道。伶仃洋港口航道的主要问题是泥沙淤积问题。基于现场实测资料分析、卫星遥感分析、泥沙水槽试验、港池淤泥密度测量与分析等手段,对伶仃洋港口航道的泥沙问题进行综合分析和研究,包括泥沙运动动力条件特征、泥沙来源与运移形式、悬沙和底质特征、港口航道泥沙淤积特征及机理、泥沙水力特性试验、浮泥及适航水深利用等,并根据伶仃洋港口航道泥沙特点提出南沙港区港口航道维护对策。Lingdingyang Bay is an important estuary bay in South China with important shipping functions,and there are important ports such as Nansha Port of Guangzhou Port,Western harbors of Shenzhen Port and Zhongshan Port on its east and west shores,and Lingding Channel and Tonggu Channel are important sea accesses for Guangzhou Port and Shenzhen Port.The major problem of harbors and channels in Lingdingyang Bay is sediment siltation.Based on the analysis of insitu data,remote sensing analysis,flume test,and measurement and analysis of silt density,we carry out a comprehensive analysis and study on sediment problems of harbors and channels in Lingdingyang Bay,including dynamic condition features for sediment movement,sediment sources and transport forms,characteristics of suspended load and bedload,sediment siltation features and mechanism of harbors and channels,hydraulic characteristic test of sediment,and fluid mud and nautical depth utilization.Maintenance countermeasures of harbors and channels are proposed based on the siltation characteristics of Lingdingyang Bay.
