In recent years, with the rapid development of tunnel construction in China, length tunnels has continued to increase, and consequent disease detection attracted more attention from maintenance departments. Among many diseases, lining cracks are most common, which directly reflect stress lining, is very important for study diseases. view current status requirements, this article carried out res...

Abstract The tunnel lining systems act as lines of defence against the forces and geotechnical situations. use precast concrete linings (PCTLs) has been escalating due to its effective economical installation process. tunnels usually suffer from premature deterioration corrosion reinforcement thus need maintenance. Corrosion leads distress in PCTL leading cracking finally scaling concrete. This...
