Abstract: Based on the calculation theory of load structure method on tunnel, the mechanical simulation model of the highway tunnel lining disease of lining thickness was established, and the reinforcing with bonding steel plates was analyzed. The highway tunnel lining damage and reinforcement mechanics simulation software was developed to evaluate the bearing capacity of lining diseases and bonding steel plate. Combined with the tunnel of the highway, the software was used to analyze the influence that second lining defects, such as inadequate arrangement of reinforcement and insufficient thickness on the structural safety and put forward the method to strengthen the structure with bonded steel plates. The safety of the structure after treatment by establishing the calculation model of bonded steel plate was analyzed to verify the rationality of reinforcement measures.
