小跨径圬工板拱加固设计与施工方法研究

Study on Reinforcement Design and Construction Methods of Small-span Masonry Slab Arch

摘要:

针对设计施工图纸缺失的小跨径圬工拱桥，通过从原桥基本参数的确定、加固设计分析与施工方法分析，结合工程实践验证此类桥梁的加固设计与施工方法的可行性，提供一套完整的加固设计施工方法。圬工板拱加固成功工程实例表明整个加固流程技术是可行的, 该综合加固设计与施工技术可为同类型桥梁的加固设计及施工提供一定的借鉴作用。

Abstract:

Aiming at the small-span masonry slab arch bridge without the design and construction drawings, the feasibility of the reinforcement design and construction methods of this kind of bridge are verified through the determination of the basic parameters of the original bridge, the analysis of reinforcement design and construction methods and combined with the engineering practices. A complete set of reinforcement design and construction methods is provided. The successful engineering cases to reinforce the masonry slab arch indicate that the whole reinforcement process technology is feasible. The reinforcement design and construction technologies can be referred for the reinforcement design and construction of the similar bridges.
