摘　　要：采用实测资料分析了吕四海域自然条件、海床稳定性和三夹沙南航道一期工程回淤情况,基于港区规划、自然条件、通航安全等因素,提出了2个航道选线方案,并采用潮流泥沙数学模型、船舶操纵模拟和统计分析等多种手段进行了比选研究。研究结果表明,西线方案水深较好,工程量和投资最小,且与港区规划适应性较好,航道回淤量可控,可作为5万t级航道的推荐轴线方案。Real-measured data were used to analyze Lusi Sea area,covering local natural conditions,seabed stability and the siltation caused by Sanjiasha South Channel Phase-1 Project.Based on harbor planning,natural conditions,navigation safety and etc.,two route selection plans are proposed and compared by means of tidal current and sediment mathematical model,ship maneuvering simulation and statistical analysis.The results show that the western route plan is characterized with appropriate water depth,the minimum amount of work and construction cost,high adaptability to harbor planning,and controlled amount of siltation within the range of channel.The above axis plan is recommended for the channel for ships up to 50000 t.
