摘　　要：随着地铁建设的加快,地铁既有车站和区间隧道在运营过程中容易受到周边施工的影响,对地铁运营安全造成威胁。为保证地铁的安全运营,就要在地铁保护区范围内进行地铁运营监测。地铁的运营监测对时效性和监测频率要求都比较高,传统的监测手段无法满足地铁运营实时监测需求。据此,文章采用测量机器人和静力水准自动化监测两种不同方法对既有换乘车站进行监测,并将两者的监测数据进行对比分析。结果表明,采用自动化监测技术手段能够对既有地铁结构变形实施实时有效监控,相关单位也能够根据监测结果及时调整施工参数及措施,保证施工期间既有地铁线路的安全运营。With the acceleration of subway construction,the existing subway stations and section tunnels are easily influened by surrounding construction during operation period,which is harmful for the safety of subway operation.In order to ensure the safe operation of the subway,it is necessary to carry out subway operation monitoring within the subway protection area.The subway operation monitoring requires high timeliness and monitoring frequency.The traditional monitoring methods can not meet the real-time monitoring needs of subway operation.In this paper,two different methods,measuring robot and static leveling automatic monitoring,are used to monitor the existing transfer station,and the monitoring data of the two are compared and analyzed.The results show that the automatic monitoring technology can effectively monitor the structural deformation of the existing subway in real time,and the relevant units can timely adjust the construction parameters and measures according to the monitoring results to ensure the safe operation of existing subway line during construction period.
