摘　　要：随着近年来深海及海洋资源开发,其装备需求也持续快速增长,相继出现大量新型构型海上系泊结构,相应的海上运输作业中出现了更多的多浮体系统。因此,对于浮体运动响应与受力等研究已成为设计所关注的重要问题。文章主要针对一种多船构成的海上多浮体过驳平台进行系泊特性物理模型试验研究,基于各船体的水动力因素以及浮体间相互作用的机理,试验得到在风浪流作用下整个系统绕单锚泊点漂移量,以及在相同环境条件作用下,各浮体的运动量与相对位移,同时对系泊浮体间的系泊缆力变化进行了测试。该试验为验证与分析这一类多浮体过驳结构的水动力性能和结构荷载提供依据,具有一定的工程实践意义。As the offshore and marine resources development in recent years,its equipment requirements also show continued rapid growth. There appeared a lot of new configuration mooring structure,and more multi-body floating system has appeared in the field of maritime transport. Therefore,the research on movement response and stress of floating body has become an important problem to design. The study of mooring characteristic of physical model experiment was carried out in this paper,focusing on a multi-vessels floating overside platform system. Based on the hydrodynamic factors and mechanism of action for interaction between floating bodies,the drift of whole system around the single anchor under the action of wind was obtained,as well as the movement and the relative displacement of floating bodies under the same conditions. At the same time,the line force between mooring floating bodies was tested. This experiment will provide a basis for the verification and technical analysis of hydrodynamic performance and structural load for this kind of multi-body floating system. It has certain significance for engineering practice.
