圬工拱桥加固改造方案探讨

Discussion on Strengthening and Reforming Scheme of Masonry Arch Bridge

文中以某地圬工拱桥为例,对旧桥进行技术状况评定并提出应对措施,根据桥梁实际结构验算提出多种加固方案并进行比选,根据圬工旧拱桥加固的原则,并在此基础上提出了针对性施工设计方案,为圬工拱桥加固改造的后续研究提供了坚实的基础,为旧桥加固提供借鉴。

Taking a certain masonry arch bridge as an example,this paper evaluates the technical status of the old bridge and puts forward the corresponding measures.According to the actual structural checking calculation of the bridge,a variety of strengthening schemes are proposed and compared.The strengthening principles of the old masonry arch bridge are proposed in the study,and on this basis,the targeted construction design scheme is proposed.This study provides a solid foundation for the follow-up research of masonry arch bridge reinforcement and provides a reference for the reinforcement of old Bridges.
