摘　　要：为了探究大型驳船的船尾槽口对其水动力特性和运动性能的影响程度,本文以浮托安装为工程背景,对较分析了某T形驳船在7种装载状态下的水动力特性,发现槽口对其横摇和纵摇响应幅值算子(Response amplitude operator, RAO)有显著影响。进一步研究了槽口在长度、宽度和坡度等不同形状参数下驳船横摇和纵摇RAO的变化趋势,揭示了槽口形状对驳船水动力特性的影响程度和影响规律。建立了波浪作用下系泊缆-驳船耦合动力模型,对比了有、无槽口两种情况下驳船的横摇响应及能量谱密度,发现了槽口对驳船的运动性能也有较大影响,对驳船横摇最大运动幅值的影响程度可达到19.8%。For exploring the influence of stern slot of large barge on its hydrodynamic and motion performance, float-over installation is taken as the engineering background in this paper, and the hydrodynamic characteristics of a T-shaped barge under different loading conditions are analyzed. It is found that the slot has a significant influence on the rolling and pitching motion response amplitude operator(RAO). Furthermore, the change trend of RAO in the roll and pitch motion of barge under different shape parameters such as length, width, and slope of the slot is studied, and the influence degree and influence law of slot shape on the hydrodynamic characteristics of barge are revealed. The coupling dynamic model of mooring line and barge under wave action is established. The rolling response and energy spectrum density of barge under the condition with or without slot are compared. It is found that slot also has a great influence on the barge motion performance, and the influence degree on the maximum amplitude of barge roll can reach 19.8%.
