采用柔性纤维材料作为结构增强构件建立了一种基于FRP的新型预制圬工拱桥结构来增强结构可持续性。该结构体系不需要进行现场浇筑和使用钢筋作为配筋材料，施工中仅需要将扁平封装好的预制拱圈在现场吊装成圬工拱体即可。采用结构试验的方法对该圬工拱桥结构进行分析，分析结果表明该结构体系的承载能力和变形情况均满足现行规范的要求。

Many bridges built of modern materials , such as steel-reinforced concrete , have required extensive repair after being in service for a relatively short period of their design life .A novel precast masonry arch bridges reinforced with polymer rein-forcement were developed to improve the structural sustainability .This flexible masonry concrete arch system requires no in -situ casting in the construction phase or steel reinforcement in the long -term service .The arch is constructed from a ‘flat pack ’ system by use of a polymer reinforcement for supporting the dead load but behaves as a masonry arch once in place .This paper revealed an experimental study of this flexible masonry arch bridge .It was found that loading -carrying capacity and deformation behaviour of this arch bridge could satisfy the requirement of current design code .
