航站楼改扩建工程钢屋盖自动化监测技术

Automatic Monitoring Technology in Steel Roof of Reconstruction and Expansion of Terminal

该工程属于改扩建工程,其中航站楼原主体结构及钢屋盖进行保留并加固。原钢屋盖桁架体系复杂,存在跨度大,荷载大,受力复杂,为保证结构安全,需对结构的重点部位在施工阶段进行监测,掌握其安全状况。

The project discussed in this paper is a reconstruction and expansion project,in which the original main structure of the terminal building and the steel roof are retained and reinforced.The original steel roof is a complex truss system with large span,large load and complex force.In order to ensure the safety of the structure,it is necessary to monitor the construction of the critical parts and master its safety status.
