摘　　要：以半潜式平台横撑为研究对象,以某型3 000 m深水钻井平台为基础,在相近横撑设置与相同环境载荷的条件下,对鼓形截面和圆形截面的横撑进行比较;对比分析了总强度载荷作用下,横撑与立柱加强结构的响应以及横撑与立柱连接处的疲劳寿命、结构布置和结构质量等,为后续平台设计提供参考。This paper takes horizontal brace of semi-submersible platibrm as study case. Based on a 3000 m depth drilling platform ,the horizontal brace of drum type and circular type are compared under the approximate brace location and the same environment loads. It compares the stress response of enhanced structure for horizontal brace and stand ,and the fatigue life ,structure arrangement and mass of connection between them ,which provide. references for the following platform design.

关 键 词：半潜式平台 横撑设计 结构强度 疲劳
