某大跨径钢筋混凝土拱桥的加固实例

Consolidation case of some large-span reinfored concrete arch bridfe

以一座钢筋混凝土拱桥加固改造工程为例,对病害进行了仔细调查,经分析,超载和承载能力低是导致其出现病害的根本原因,通过对主拱圈套箍加固和混凝土剥落部位进行灌封闭胶等措施来提高结构承载能力,效果良好。

In this paper,a reinforced concrete arch bridge reinforcement project as an example,the disease was carefully investigated,through analysis,overload and low bearing capacity is the primary cause of the disease,through irrigation and other measures to improve the structure of sealing capacity of the main arch hoop reinforcement and concrete spalling area,good effect.
