Abstract: The rapid economic development requires more and more waterway transport, lots of ships are in the dock for a longer period of outfitting operations and are frequently hit by major storms or even typhoons to keep the ship and the pier safe which is one of the key issues concerned in this field. The test process is detailed, large container dock at issue, the author of this paper, with a wave cycle and amplitude is variable, layout optimization of mooring system, carry out multi-loading combined large container ship mooring pier related experimental research, explore the movement characteristics of ships, the top of the mooring line tension, for the future design of large ship's mooring system to provide the reference and guiding significance.
Key words: large container     quay mooring     working condition     movement characteristic

6 结　语

1）由于甲板驳船的船型特殊性，采用双首缆、双尾缆的系泊形式，试验中船舶的主要自由度运动幅值在规范规定的范围内，验证优化设计系泊缆布置形式的合理性；

2）系泊状态下船舶横荡、垂荡和横摇运动幅值，随着波浪周期的增大而增大，随着波幅的增加而非线性增加；

3）系泊缆索的顶端张力变化时历曲线符合规则波作用的特性，在预张力的基础上，围绕平衡位置波动，系泊缆索的顶端张力随着波幅的增加而增大。
