随着我国交通事业的快速发展,部分旧公路桥梁的设计荷载等级已不能要求满足,有些投入运营不久的桥梁,由于设计或施工原因,也出现开裂或挠度过大的现象,因此需要对已有桥进行加固改造。本文对国内部分病害桥梁加固实例进行了加固技术方面的分析总结,做了一些补充,对桥梁设计工作也会有
With the rapid development of transportation in our country, the designed load rating of some old highways and bridges can not meet the requirements. Some bridges put into operation shortly have cracking or excessive deflection due to design or construction. Therefore, Bridge reinforcement. In this paper, some examples of strengthening the bridges in our country are analyzed and summarized in the aspects of reinforcement technology. Some supplements are made to the bridge design work.
