摘　　要：针对大跨度双曲网壳钢结构在施工过程中单元拼装及吊装量大、精度要求高等难点,在施工前根据设计图纸对施工过程进行模拟优化,对于保证大跨度双曲网壳钢结构屋盖工程的顺利施工以及建筑工程安全十分重要。本文以广东某国际会展中心主体超大跨空间钢结构为例,进行大跨度钢结构屋盖体系节点的受力分析,以及双曲网壳架单元吊装施工模拟。结果表明,吊装单元的施工模拟可以保证双曲网壳架单元吊装不变形及整体稳定性。此外,本文通过精准控制模拟三维坐标、实测三维坐标与控制点坐标拟合能够保证钢结构整体安装质量,节约工期,创造良好的经济和社会效益。In view of the difficulties in the construction of long-span hyperbolic reticulated shell steel structure,such as large amount of unit assembly and hoisting,high precision requirements and so on.It is crucial to simulate and optimize the construction process in accordance with the design drawings before construction to ensure the smooth construction of the long-span hyperbolic reticulated shell steel structure roof project and the safety of the construction project.Taking the large-span spatial steel structure of an international convention and exhibition center in Guangdong as an example,this study carried out the stress analysis of the joints of the large-span steel structure roof system and simulated the hoisting construction of hyperbolic reticulated shell units.The results demonstrated that the hoisting unit construction simulation can guarantee the overall stability of the hyperbolic reticulated shell unit without deformation during hoisting.In addition,by precisely controlling simulated 3D coordinates,measuring 3D coordinates,and fitting control point coordinates,this paper can guarantee the overall installation quality of steel structure,shorten the construction period,and generate more economic and social benefits.
