摘　　要：厦门国际会展中心主体屋盖为双向大悬臂空间桁架结构 ,其中 35m跨悬挑桁架采用地面分段拼装、空中无支撑接装组拼、塔机分榀顺次退吊工艺 ,确保了结构的整体稳定、受力合理 ,减少施工投入 。The roof of the main building of Xiamen International Meeting and Exhibition Center adopted the two\|direction large overhanging spatial bar\|frame structure. Its overhanging bar\|frame, whose span is 35m, was divided into several sections and assembled separately on the ground, and finally was integrated in the air without any supports. The removal of tower cranes was used the sequential piece\|by\|piece method to ensure higher whole stabilization of structure, more proper stress distribution, lower constructional input, and quicker progress.
