Abstract
Deformation can reflect the state of the surrounding rock in excavation process,and basis for the stable state of underground works,So deformation monitoring and analysis of monitoring information feedback throughout the NATM tunnels construction course.Study of soft rock section of the Dagui mountain tunnel with NATM based on the monitoring information,this thesis put forward some opinions which guidance of the tunnel construction with NATM,and could be taken as a significant references to similar projects.
