有粘结预应力体系在公路桥梁加固中的应用

Application of the bonded prestressed system in the highway bridge reinforcement

结合工程实例,通过对箱涵顶板裂缝的加固方案进行比选,得出箱涵顶板底面有粘结预应力体系加固方案为推荐方案,对其工艺流程及特点进行了分析,最后对其加固效果作了评价。

Combined with the engineering example, the author obtains that the reinforcement scheme of the bonded prestressed system on the roof and the bottom surface of the box culvert can be used as the recommended scheme through the comparison of the reinforcement scheme of the cracks on the roof of the box culvert, analyzes the technological process and the characteristics, and finally evaluates the reinforcement effect.
