以某预应力混凝土T型刚构箱梁桥为背景,对采用不同加固方案的优缺点进行比选，最后从技术可行性和经济角度推荐采用碳纤维CFRP加固方案。并给出了加固的具体实施方案和要点。其研究成果可为相关桥梁的维修加固施工和设计提供参考。

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.
