摘要
本项目采用高标塔、BIM全站仪、三维激光扫描、CORS、多源数据融合等测量技术组成的关键测量技术,实现对北京大兴国际机场航站楼特大钢结构工程安装空间位置的高精度检测与调整,并对卸载后的钢结构进行安全监测。本文详细介绍了北京新机场特大钢结构施工测量的各个环节智能测量技术的应用,为后续特大异型钢结构施工提供借鉴。
In this project,key measurement technologies,such as high-level tower,BIM total station,three-dimensional laser scanning,CORS and multi-source data fusion,are used to realize high-precision detection and adjustment of installation space position of Beijing Daxing International Airport Terminal’s extra large steel structure project,and safety monitoring of unloaded steel structure.This paper introduces in detail the application of intelligent measurement technology in each link of construction measurement of extra large steel structure in Beijing new airport,which provides reference for the subsequent construction of extra large special steel structure.
