摘要
为解决传统外部粘贴纤维或钢板加固桥梁技术的被动性,以某箱型桥梁为例,提出采用"体外预应力钢绞线+粘贴碳纤维布"的措施对主梁结构进行补强;通过对其进行加固前后结构检算分析,结果表明该加固方法可达到设计预期;最后提出相应施工方法,可为同类工程提供参考。
To sovle the passivity of traditionally external bonded fiber or steel plate technology to reinforce bridge, combining an example of a box - type bridge, the paper proposed to use the method of ＂external prestressing technology ＋ carbon fiber sheet （CFS） ＂ to reinforce the main beam, and then conducted a structure calculation analysis before and after the reinforcement. , which show satisfactory effect on the design expectations. Finally, the paper proposed the corresponding construction program which may provide useful reference for similar projects.
