摘　　要：根据厦门站大跨度拱形钢网架屋盖结构的受力特点和场地条件,采用地面分块拼装,高空分区分段拼装累积滑移的施工方案。从施工吊装、滑移、变形控制、卸载等方面叠合使用工况载荷进行了全过程的计算仿真分析,为此类钢结构的施工提供了借鉴。According to the stress characteristics and site conditions of the large-span arch steel space truss roof structure of Xiamen station,the construction scheme of ground block assembly and high-altitude subdivided and segmented assembly and accumulated sliding is adopted.From the aspects of construction hoisting,sliding,deformation control,unloading,etc.,the whole process of calculation and simulation analysis is carried out by using the superposition of the working loads,which provides a reference for the construction of this kind of steel structures.
