Abstract: It is of great significance to monitor the structure of subway tunnels to ensure the safe operation of subways. At present, the intelligent total station instrument is applied more and more widely in the automatic monitoring of the subway tunnel structure, and the monitoring accuracy it can achieve is also attracting attention. Combined with the basic mathematics model of deformation monitoring with intelligent total station, the accuracy of its application in subway tunnel monitoring is analyzed, and its monitoring accuracy is also verified in the actual subway tunnel.

Key words: tunnel monitoring, intelligent total station, accuracy analysis
