摘　　要：广东某机场航站楼应用大截面异形斜柱支撑屋面网架结构和悬挂外立面玻璃幕墙。大截面异形斜柱施工在现有的公共建筑中为数不多,对施工成型是一项重大的考验。项目通过应用BIM模型模拟施工、放线定位、钢柱安装、大直径钢筋安装、定型化模板安装、支撑体系加固、混凝土浇筑、拆模与养护等施工总结,并对施工过程中相关资料与技术方案的整理汇总和分析,形成了一套成熟可靠的大截面异形斜柱施工关键技术,为其他类似工程建设提供技术支持。A large-section special-shaped inclined column is used to support the roof grid structure and suspend the facade glass curtain wall in an airport terminal building in Guangdong.Large cross-section special-shaped inclined column construction is a major test in the exist‐ing public buildings.Through the application of BIM model to simulate the construction,laying line positioning,steel column installation,large diameter reinforcement installation,stereotyped template installation,support system reinforcement,concrete pouring,stripping and main‐tenance construction summary,and the collection and analysis of relevant information and technical scheme in the construction process,a set of mature and reliable key technology of large section special-shaped inclined column construction is formed,which provides technical sup‐port for other similar projects.
