摘　　要：施工过程监测对复杂大跨空间结构的安装与施工具有重要意义。根据施工方法的不同,施工监测应选用针对性的监测指标。该文对大跨空间钢结构施工过程常用的监测指标与相应的监测手段或设备,以及新型监测技术进行详细地分析研究。结合北京新机场航站楼核心区钢结构屋盖施工过程,综合选取关键杆件应力应变监测、基于三维激光扫描的位移与变形监测以及重点区域无人机监测等手段,对结构施工过程的受力特征、变形与部分施工质量问题进行详细监测和检查。该综合监测技术为复杂大跨空间钢结构的施工提供了全面可靠的解决方案。Construction process monitoring is of great significance to the construction of complex large-span spatial steel structures. The targeted monitoring indicators should be chosen according to different construction methods specifically. The commonly-used monitoring indicators and the corresponding monitoring methods and devices during the process of the construction monitoring of large-span spatial steel structures, and new monitoring technologies are discussed in detail. Based on the construction process of the steel roof of the Beijing New Airport terminal building, the monitoring indicators including the stress and strain of key components, structural displacement and deformation by using 3D laser scanning and UAV monitoring of priority areas are selected comprehensively to inspect the mechanical behavior, deformation feature and partial construction quality problems of the structure. This comprehensive monitoring technology provides a comprehensive and reliable solution to the construction monitoring of complex large-span spatial steel structures.
