Research about Data Processing for Tunnel Deformation Monitoring Based on GPS Monitoring Technique

The use of GPS is mainly focused on the slope deformation monitoring for highway safety monitoring, both at home and abroad; but, the research about GPS monitoring data for concealed works, such as tunnels, is little. Because of its advantages, it is a trend that GPS monitoring technique will be used for tunnel deformation monitoring. This paper uses the GPS monitoring technique to monitor the deformation of DA Shan-Po Tunnel in real time, and verifies the feasibility of the GPS monitoring technique used in the DA Shan-Po Tunnel through data processing and analyzing. We hope that the study will provide reference for similar projects.
