Abstract:

On basis of a prestressed concrete Ttype rigid frame box girder bridge, the paper compares the advantages and disadvantages of different reinforcement options. From the viewpoint of technical feasibility and economic efficiency, the paper recommends that the option of CFRP reinforcement should be adopted. The paper also provides a general description and key points of the CFRP reinforcement option, which article canprovide reference for the design and construction of the reinforcement of similar bridges in the future.
