随着我国城镇化进程的不断推进,城市规模日益扩大,人流量和车流量逐渐增加。城市中一些旧桥由于年久失修,导致病害增多,而最初桥梁设计考虑的荷载等级偏小,已经越来越不能满足发展的要求。因此,桥梁加固修补技术对减缓桥梁病害的发展和提高其原有的承载等级,不失为一种既行之有效又经济节约的手段。结合太原市汾河管线桥维修加固工程的施工,针对钢筋混凝土桥梁结构常见的病害和加固补强方法进行探讨。
With the continuous progress of urbanization in our country, the scale of cities is expanding day by day, and the human traffic volume and traffic volume are gradually increasing. Due to the disrepair of some old bridges in the city, the diseases increase, but the load level designed by the original bridge is too small to meet the requirements of development. Therefore, the bridge reinforcement and repair technology to reduce the development of bridge disease and improve its original bearing level, after all, is an effective and economical means. Combined with the construction of the Fenhe pipeline bridge repair and reinforcement project in Taiyuan City, the common diseases of the reinforced concrete bridge structure and the reinforcement and reinforcement methods are discussed.
