摘　　要：基于屈曲分析理论,以400英尺自升式钻井平台为研究对象,分析大尺度桩靴结构板材的屈曲强度。利用SESAM软件,建立桩靴结构有限元模型。参考ABS规范,选取最不利工况,并通过自编VBA程序,对桩靴受压板材高应力区进行屈曲分析。研究工作保证了海洋平台桩靴设计的安全性,并提供了屈曲强度的快捷计算方法。Based on buckling analysis theory,taking 400 ft jack-up drilling platform as a research object,the buckling strength of large scale spud can structural plate is analyzed.The finite element model of spud can structure is established by SESAM software.Referring to the ABS Code,the most unfavorable working conditions are selected,and the buckling analysis of the high stress area of the spud can compression plate is carried out through the self compiled VBA program.The research has ensured the safety of offshore platform spud can design and provided a quick calculation method for buckling strength.
