| 摘 要： | 介绍了双曲拱改建成刚架拱这种结构体系转换加固拱桥的技术.对新结构体系的基本假定、计算方法和原理进行了研究,并对2种不同跨径的桥型的结构内力进行了对比.研究结果表明:刚架拱的受力性能优于双曲拱桥,且其拱上建筑轻于双曲拱,可为将双曲拱改建为刚架拱提供理论依据.

| Abstract: | This article introduces the technology of conversion and technology of structural system in double-curved arch bridge transformed into rigid-framed arch bridge,researching basic assumption,calculation method and principle of new structure,and contrasting internal force of two different span bridge.The rigid-framed arch bridge is superior to double-curved arch bridge in force capacity,and building is lighter than double-curved arch bridge on main arch that it provides basis theoretical for double-curved arch bridge transformed into rigid-framed arch bridge. |
