AI Technical Summary
Traditional steel reinforcement methods for tunnel linings suffer from poor interfacial bonding reliability under temperature loads, and the steel plates are prone to rusting and require significant maintenance, thus affecting the reliability and durability of the reinforcement.
Carbon fiber plates are used to reinforce tunnel lining. By coating a smoothing layer on the surface of the tunnel lining, fixing the carbon fiber plates with fixing hoops and anchors, and coating the contact surface with an adhesive layer and a buffer layer, the mechanical locking and adhesive layer work together to eliminate stress concentration. The lightweight and corrosion-resistant properties of carbon fiber plates are used to improve the structural strength and durability.
It enhances the load-bearing capacity and crack resistance of the tunnel lining structure, reduces the material's self-weight, avoids peeling caused by temperature changes, and improves the structural durability and corrosion resistance of the tunnel lining.
