滑道梁是海上平台用来拆装维修的重要工具.由于平台结构的特殊性,滑道梁结构差别很大,其强度的校核计算相当复杂.文章对滑道梁系统进行大量力学分析,并从工程计算的角度对其复杂的力学模型进行合理简化,以钢结构承载能力极限状态为准则,推导出滑道梁校核的一般通用性方程,为工程设计提供可行的计算依据.%The sliding way beam is an important tool for the disassembly and the maintenance of the offshore platform. It differs greatly in structure due to the particularity of various platforms, resulting in extremely complex strength check. This paper performs the numerous mechanical analyses of the sliding way beam system, and makes reasonable simplification of the complex mechanical model from the engineering viewpoint. It deduces the general equation for the check of the sliding way beam according to the ultimate bearing capacity of the steel structures, which can provide the reasonable computational basis for the engineering design.
