[0002] Compared with flat plates, corrugated steel plates have better bearing strength. They are new types of supporting building materials and are widely used in the production of culverts, tunnels, underground passages and underground pipeline supports. During the construction process, in order to improve the bearing capacity of corrugated steel plates, external auxiliary reinforcement structures are often required. External reinforcement structures include steel structure reinforcement and reinforced concrete reinforcement. When using reinforced concrete structures to enhance the bearing capacity of corrugated steel plates, the effective connection between the reinforced concrete structure and the corrugated steel plates becomes the key.
