摘　　要：对无横撑六立柱半潜平台的结构强度进行研究。总结该平台的研究现状,阐述其结构总强度分析流程,介绍该类型平台总强度分析的计算工况,确定目标无横撑半潜平台的设计波参数,探讨结构重点关注区域。通过与传统四立柱平台的结构总强度计算结果相对比,分析六立柱半潜平台与四立柱半潜平台在总强度方面的差异。通过对有无横撑2种型式半潜平台结构的应力情况进行对比,分析横撑结构在该类型平台设计中应用的必要性,为无横撑半潜平台的结构设计提供参考。A study is carried out for the global strength of six-column semi-submersible platform without cross brace. This paper summarizes the study status of the semi-submersible platform without cross brace, describes the analysis process of the global strength of semi-submersible platform, introduces the main loading conditions of global strength analysis for this type of semi-submersible platforms, determines the design wave parameters of the target semi-submersible platform, and discusses the structural areas that need special attention. The difference of global strength between the six-column semi-submersible platform and the four-column semi-submersible platform was analyzed by comparing the results of global strength calculation of the two platforms, and the necessity of the cross-brace structures for such platform design is analyzed by comparing the structural stresses between the two platforms either with or without the cross brace, which provides reference for the structural design of semi-submersible platforms without cross brace.
