摘　　要：泊位长度与系缆方式影响系泊船舶的运动量和系缆力,泊位长度确定和系缆方式选择是大型开敞式码头设计中的一个重要课题。以17.2万m3LNG船为研究对象,通过物理模型试验,研究风、浪、流共同作用下系泊船舶的运动量和系缆力,分析泊位长度与系缆方式对系泊船舶的影响,研究结果表明:较短的泊位长度对横向运动、缆力大小以及缆力间的均匀性有一定的改善;在横风横浪作用下,短泊位时横缆分开布置对船舶运动有较好的约束,能减小艏艉缆及倒缆的受力,而在泊位较长时,横缆应集中布置,避免横缆长度不一,较短的横缆承担较大的作用力。The berth length and mooring method are the influential factors on the ship movement and mooring force.The determination of the berth length and the choice of the mooring method are an important issue in the design of large open wharf.Based on the physical model experiment with a 172,000 m3 Liquefied Natural Gas(LNG)ship,the influence of mooring method and berth length was analyzed through the test data.According to this research,shorter berth length is conducive to reducing lateral motion and cable force and improving the uniformity of cables.In the case of cross wind and beam wave,separately arranging breast cables is recommended in short berth,which not only can be good at restraining the transverse movement of the ship,but also can be conducive to reducing the mooring force.However,when the berth is longer,the breast cables should be arranged concentratedly to avoid the condition that the length of the breast cables is different.Because under this condition,the shorter breast cables are subjected to the greater force.
