摘 要: | 笔者针对大跨度双曲拱桥的病害特点,探讨了同时采用局部增大主拱圈截面、增加横向联系和改变拱上建筑结构体系三种措施来加固改造危旧双曲拱桥,避免了对主拱圈整体进行维修加固的麻烦.该方法已成功运用于重庆市巫溪县110m净跨的大宁河大桥的维修加固工程中,取得了很好的社会经济效益.

Abstract: | A method to strengthen a bi- curved arch bridge is presented according to the damage situation of the bridge. Three measures of enlarging the local sections, strengthening the bracings and changing the form of super-structure are used to avoid the trouble of repairing the whole main-arch.
