我国的国民经济的发展,带动了交通运输业的发展,交通量的增大以及交通工具的超载现象使运营多年的桥梁结构会出现许多病害,影响了结构的安全性,所以要进行桥梁的加固。本文分析了在不中断公路通行条件的前提下进行桥梁加固的技术方案以及加固效果的验证,最后对桥梁加固技术进行了总结。 The development of the national economy in our country has led to the development of the transportation industry, the increase of the traffic volume and the overloading phenomenon of the transportation vehicles. Many diseases will occur in the bridge structure that has been operating for many years, which will affect the structural safety. Therefore, it is necessary to reinforce the bridge . This paper analyzes the technical scheme of strengthening the bridge without interrupting the traffic conditions of the highway and the verification of the reinforcement effect. Finally, the paper summarizes the technology of the bridge reinforcement.
