Design on Integral Monitoring System for Subway Tunnel Construction Based on GPS and Surveying Robot

At present, the comparative deformation in the inner of the tunnel is attached more importance to during soft-soil tunnel construction, so when taking tunnel analysis and design, we think much of comparative deformation in the inner of the tunnel. As a matter of fact, inner and outer deformations of the tunnel are a uniform organism, none but considering and analyzing both inner and outer deformation of the tunnel conjunctly, it is much better to ensure the quality of tunnel construction. Therefore, the writer and research team put forward the thought concerning inner and outer deformation integrated monitoring for the tunnel construction as well as offer corresponding monitoring method and technical instrument. An integral monitoring system for external and internal deformation of tunnel based on GPS and Surveying Robot has been developed.
