双曲拱桥在我国数量较多且运营时间较长,当前大都存在较多的病害,影响行车安全,文章通过对一典型双曲拱桥的维修加固实例分析,对比加固前后的静力荷载试验数据,表明对大多数的双曲拱桥进行维修加固提高其承载能力和通行安全性及耐久性,改善桥梁技术状况,节省养护资金投入具有积极的意义。 In our country, the number of double-curved arch bridges is relatively large and the operating time is long, and most of the existing diseases present most of the problems affecting traffic safety. By analyzing and comparing the static load test data of a typical double- It shows that it is of positive significance to repair and improve most of the double curved arch bridges to improve their carrying capacity, traffic safety and durability, improve the technical condition of bridges and save the investment of conservation funds.
