摘　　要：以某项目多层多单体大跨度会展施工为例,主要介绍大型会展施工中采用大跨度桁架无临时支撑安装技术、多层桁架综合安装技术、大型履带吊进入地下室顶板上部施工技术。通过对上述技术的研究与应用,降低了大量施工措施,保障了现场施工进度和质量安全。Taking the multi-storey multi-unit large-span exhibition construction of this project as an example,this paper mainly introduces the large-span truss installation technology without temporary support,multi-storey truss comprehensive installation technology and large-scale crawler crane entering the upper part of basement roof construction technology in large-scale exhibition construction.Through the research and application of the above technologies in this project,a large number of construction measures are reduced,and the construction progress and quality safety of the site are guaranteed.

关 键 词：大跨度 钢结构 桁架
