摘　　要：由于设计的缺陷和交通量的迅猛发展,相当多的双曲拱桥出现了大量的病害。文章采用结构损伤识别的方法来修正计算模型的边界条件或计算模型的材料参数取值,判断结构损伤对桥梁内力的影响,以期为双曲拱桥的加固维修提供更为准确的设计依据。Due to the design flaws and the rapid development of traffic,a considerable quantity of two-way curved arch bridges have appeared a large number of diseases.The articles used the structural damage identification method to correct the boundary conditions of computational model or the material parameter values of computational model,？？so as to determine the impact of structural damage on the bridge internal forces,aiming to provide more accurate design basis for the reinforcement and repair of two-way curved arch bridges.
