摘要
地铁隧道的近接施工会对其结构造成影响,产生变形,严重时会对行车安全造成重大威胁。本文利用ADMS测量监测系统对既有线地铁隧道进行自动变形监测,具体介绍了三维极坐标的测量原理和点位精度分析方法、阐述了观测值的实时差分改正模型、描述了ADMS测量监测系统的组成及其配置,并且采用ADMS测量监测系统成功实现了对既有地铁线路结构的高精度、高效率、全天候、自动化变形监测,具有较高的社会效益、经济效益和广泛的发展前景。
The subway tunnel adjacent construction would affect it＇s structure, and caused deformation, seriously could cause significant threat to the traffic safety. In this paper, used ADMS measurement monitoring system for the automatic deformation monitoring of the existing subway tunnel, detailed introduced the three dimensional polar coordinate measurement principle and the point position accuracy analysis, elaborated on the real-time differential correction model of the ob served value, described the composition and configuration of the ADMS measurement monitoring system, and used ADMS measurement monitoring system successfully monitored the metro line structure with high precision, high efficiency, all weather and automatic,The fact proved that this technique has wide market,vast economic and social efficiency.
