摘要
文章结合当前双曲拱桥加固施工实际,总结出双曲拱桥加固施工的关键流程和控制技术,并通过双曲拱桥加固施工顺序对主拱内力和位移的影响分析,确定了双曲拱桥加固施工的最优顺序,对可利用的双曲拱桥进行加固、改善和维修,提高桥梁结构的荷载等级和通行能力。
Combined with current two-way curved arch bridge reinforcement construction practices,this article summarized the reinforcement processes and control technology for two-way curved arch bridge reinforcement construction,and determined the optimal reinforcement construction sequence of two-way curved arch bridge through the impact analysis of two-way curved arch bridge reinforcement construc-tion sequence on internal forces and displacements of main arch,which can improve the load rating and traffic capacity of bridge structure through the reinforcement,improvement and maintenance of usable two-way curved arch bridges.
