A Case Study of Distress Detection and Treatment of Loess Road Tunnel

Abstract:

Based on the characteristic of distress in Qijia mountain road tunnel, thickness, cavity distribution, crevice water were detected with geo-radar. Material of lining was nondestructive detected with sound locater. Limiting structure of the tunnel was detected with circumscription apparatus. Based on detected results cause of the distress was analyzed. Three treatment schemes were put forward by slurry injection from the back of lining structure, reinforcement lining, treating the water proof system. Stability of surrounding rock and the state of forces of the lining structure were analyzed before and after treatment. It is showed that the treatment scheme of the tunnel is feasible. Taken construction and cost estimate into account, optimal scheme is obtained.
