摘　　要：利用大型有限元ANSYS软件对各滑移单元进行施工状态计算分析,得到各滑移单元挠度分布、结构应力分布、轨道竖向反力,并对特殊工况和卸载进行计算,对张拉进行控制,以保证张拉过程的顺利进行,为大跨度钢结构屋盖滑移施工提供了工程和理论依据。In this paper,the large-scale finite element ANSYS software is used to calculate and analyze the construction state of each sliding element,and the deflection distribution,structural stress distribution and vertical reaction force of each sliding element are obtained.This paper calculates the special working condition and unloading,and controls the tension to ensure the smooth progress of the tension process,which provides the engineering and theoretical basis for the sliding construction of large-span steel structure roof.

关 键 词：屋盖 滑移 控制 ANSYS分析
