摘　　要：该文针对九龙江河口湾顺岸码头多次出现系泊船舶漂移情况,在现场调研和分析的基础上利用排除法初步确定了主要影响因素。根据现场实测水文、地形等资料,采用潮流数学模型和船舶系泊物理模型对该集装箱泊位的水流结构及船舶漂移过程进行了模拟试验。根据试验结果研究了河口湾大潮差环境下系泊船舶漂移的主要影响因素,并据此提出了有关工程措施和建议。研究结果表明,由于码头边界引起的局部特殊水流是该泊位系泊船舶漂移的主要水动力因素,通过延伸导流堤和疏浚措施能够改善水流和受力条件,降低船舶漂移风险。To solve the drift accident of mooring ship at the alongshore jetty in Jiulongjiang estuary of China, the main influence factors are determined initially by exclusive method after field survey and analysis. Based on the data of hydrology and bathymetry measured at site, the current structure and mooring ship drift process are simulated using mathematical model and physical model. According to the test results, the main influence factors and mechanism on drift of mooring ship in large tidal range conditions of estuary are studied, and some concern engineering measures and suggestions are proposed. The study result indicates that the main hydrodynamic factor is the local special flow due to water front at wharf, and the risk of drift will be reduced by extending the diversion dike to improve the current and stress conditions.
