Monitoring the Ground Stability of Highway Tunnels Constructed in a Landslide Area using a Web-Based GPS Displacement Monitoring System

A new type of web-based displacement monitoring system using GPS was applied to monitor the slope stability around a tunnel construction site. The system continuously provided the three dimensional displacement behavior of the slope on the web site in real time. It was very useful and effective for safely performing the tunnel construction in this project.
