城市桥梁钢筋混凝土结构加固维修技术

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和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.因此旧桥检测、加固修补技术,对减缓桥梁病害的发展和提高其原有承载等级,不失为一种既行之有效又经济节约的手段.城市中旧桥往往以钢筋混凝土桥梁居多,对...

Reinforcement and Repair Technology of Reinforced Concrete Structure of Urban Bridge

With the continuous pushing on of urbanization process in China,the city scale is increasingly broadened,and the pedestrian flow and vehicle flow gradually increase.Some old urban bridges have not satisfied the development requirements because of increasing faults in a dilapidated condition and the low load class of the primary bridge design.Therefore,the testing,inspecting,reinforcing and repairing technologies of the old bridges are the feasible,efficient,economical means to slow down the development of bridge faults and to enhance the original bearing class.The article specially discusses the common faults of the reinforced concrete bridge structure and the reinforcement and repairing method able to be referred for the similar projects.
