摘　　要：码头前系泊船的运动响应与缆绳张力对于码头的运营安全至关重要。波群对系泊浮体波浪载荷特性不同于普通的随机波浪,具有一定的特殊性。该文对两种模拟波群方法进行了讨论,分析了两种模拟波群方法的特点以及群性与波浪统计特征值之间的关系。在此基础上开展了群性波浪作用下系泊船的运动响应研究,得出了谱峰因子?、群高参数GFH和群长参数GLF与波浪特征波高的变化规律。For the stability of wharf structure vessel and cargo handling, it is a critical problem to determine the motion and mooring tension of a moored ship exposed to the action of waves. Groupiness is an important feature of ocean waves, which is different of the random wave in the affect on floating body. Two approaches of simulating the wave group are discussed to analysis the relationship of groupiness and statistic characteristics such as significant wave height. Based on the motion response of mooring ship under the wave group action, some detail results such as the influence of spectrum peak factor 2,, wave height factor GFH and wave length factor GLF on the statistic characteristics height are presented in this paper.
