简支梁桥上部结构加固对策及质量控制策略研究

Study on reinforcement countermeasures and quality control strategies for superstructure of simply supported beam bridge

我国的旧桥数量仍然庞大,而且在交通运输中还承担着很重要的角色,这些桥梁出现病害也比较多,加固方法多种多样,而如何进行合理的加固是目前研究比较热门的方向。针对行业现状,以既有的简支梁桥典型病害成因分析为基础,以本行业及相关行业的理论、规范、标准为工具,提出了路桥桥梁常见病害维修控制养护方法和路桥施工技术质量安全保障体系,完善了现有的养护规范里的病害内容,这一研究成果可应用于大量的既有公路桥梁改造工程。

The number of old bridges in our country is still huge,and it also plays an important role in transportation.There are many diseases in these bridges,and there are various reinforcement methods.How to carry out reasonable reinforcement is a hot research direction at present.In view of the current situation of the industry,based on the analysis of the causes of the typical diseases of the existing simple supported beam bridges,and with the theory,specifications and standards of the industry and related industries as tools,the maintenance methods of common diseases of road and bridge and the quality and safety assurance system of Road and bridge construction technology are put forward.The disease contents in the existing maintenance specifications are improved.This research result can be applied to a large number of existing existing bridges highway bridge reconstruction project.
