摘　　要：随着世界人口的迅速增长、内陆资源的枯竭和世界经济的可持续发展,人类逐步加大了海洋资源开发和空间利用能力的投入力度。超大型浮体结构是近几十年来海洋利用中备受关注的海洋结构之一。尽管对超大型浮体进行了广泛的研究,但仍有许多关键技术需要解决,超大型浮体结构的极限承载力就是关键技术之一。本文首先给出了经典的超大型浮体结构构型,其次针对文中的构型给出其载荷特性,然后总结分析了超大型浮体的极限强度计算方法以及试验研究,最后对超大型浮体结构极限强度研究的进展进行了讨论。The rapid expansion of world population,the depletion of inland resources and the requirement of sustainable development of world economy have strengthened the efforts of mankind to increase the capabilities of resource exploitation and space utilization in the ocean.Very Large Floating Structures(VLFS)have attracted much attention in ocean utilization among those marine structures for several decades.Despite the extensive research on VLFS,there still remain many key technologies to be solved,one of which is the ultimate bearing capacity of VLFS.This paper mainly reviews the research development of ultimate strength of VLFS,starting by the presentation of VLFS configuration and illustration of the structural load characteristics in accordance with the configuration,followed by summarization of the calculation methods of ultimate strength and the trial research on ultimate strength of VLFS,and ending with the discussion of the research development of ultimate strength.
