Loess Tunnel Lining Cracking Analysis and Monitoring System Research

Guang Yao

Abstract


With the phenomenon of loess tunnel lining cracking, tunnel lining crack was analyzed by the engineering background of Qiaoyuan tunnel. Researching tunnel crack number, width and length, tunnel stress field was established by numerical simulation. In order to maintain the long-term stability of the tunnel, establishing monitoring system with BOTDR sensing technology, positioning tunnel diseases place accurately, measures would be taken timely before arising large lining crack.
