摘　　要：武汉火车站中央站房空间网壳结构屋面采用大型滑移胎架、高空原位安装法施工。介绍在施工工期紧张及结构形式特殊等因素影响下,支承胎架的设计。长41.1m,宽32.875m,高52m,单部胎架重2740t的大型滑移胎架由滑移胎架、跨搭式桁架、钢支柱和檩条式桁架组成。对大型胎架进行了动力和静力分析,计算结果表明胎架的承载力、变形和稳定性满足规范要求。The central station building of Wuhan Railway Station uses space reticulated shell roof which is constructed by sky-high in-situ installation method with large movable jig. The authors show the design of this support jigs on the condition of short construction period and special structure style. The large movable jig, with 41. lm length, 32. 875m width, 52m height and 2 740 tons weight, consists of movable jig, cross-lapped truss, steel support columns and purlin-style truss. Dynamic and static analysis on this jig shows that load capacity, deformation and stability of this jig can satisfy code requirements.
