| Abstract: | For the existing hollow slab bridge disease, adopt different reinforced methods, such as filling the end hollow of slab with concrete, internal upsetting web plate, and pasting steel plates on the external web plate to improve mechanical behavior, and by carrying out static load test and follow -up disease checking to evaluate maintenance and reinforcement effect. It can provide some valuable reference for engineering practice. |
