CAI Gan-xu;LI Yu-cheng;Nanjing Metro Resources Development Co.ltd.;School of Earth Sciences and Engineering,Hohai University;  
The principle and method of automatic monitoring for metro protection area are discussed.Combined with the example of automatic monitoring of metro protection area,the multi direction and real-time information acquisition technology of subway tunnel structure during operation is introduced,and automatic static level measurement and control system to obtain the settlement data and automatic total station measuring and controlling system to obtain the horizontal displacement data acquisition combined with artificial monitoring data are analyzed contrast.The results show that,automatic level measurement and control system to obtain the settlement data and automatic total station measuring and controlling system to obtain the horizontal displacement data has high precision,which can meet the subway protective area automatic monitoring requirements and has good application and popularization value.
