| 摘 要： | 基于钢筋混凝土双曲拱桥建设年代久远，出现病害越来越多的情况，对拱座基础比较牢固．只是主拱圈不能满足现行交通及重车通行的钢筋混凝土双曲拱桥，结合实例进行结构受力分析，采取加固改造处理措施．提高主拱圈承载能力，使之继续发挥社会和经济效益。

| Abstract: | Based on the current situation that reinforced concrete double-curved arch bridges have long history and increasing diseases, some double-curved arch bridges have strong arch support, but can not bear the existing traffic and heavy vehicles. In order to resolve this problem, the structural force of reinforced concrete doublecurved arch bridge is analyzed through actual example, and the reinforcement measures are taken to increase the capacity of arch ring, which keeps old bridges bringing economic and social benefits. |
