摘　　要：对一采用异型截面拱加固法加固的双曲拱桥进行有限元分析和试验研究,从理论上验证该加固方法的有效性和合理性.在总结已有研究成果的基础上,利用ANSYS分析软件中实体单位对加固后的双曲拱桥进行有限元模拟,假设新老混凝土结合面不产生滑移,且能够共同参与受力.通过计算结果与试验测量值进行对比,证明ANSYS软件中实体单元分析加固后双曲拱桥的可行性.With the help of finite element analysis and experimental studies, the availability of the scheme has been proved, especially in the double curved arch bridge. After the summarization on ex- isting researching work, the paper address the scheme using finite element software ANSYS under the assumption that the interface between new and old concrete has no skip and is able to sustain forces together. By comparing computation value and test data, the feasibility of proposed method has been proved. The proposed scheme has guidance for new-aged concrete band in finite element analysis.
