摘要
阐述了桥梁加固的意义、特点及常用方法。对常用的预应力拉杆加固钢筋混凝土梁板法进行了分类介绍,重点介绍了桥梁上部结构加固中的预应力加固方法及其计算理论,以T型梁为例,介绍了补强拉杆的截面计算方法。
This paper described the significance, the characteristics and usual methods of bridge reinforcing. It classified the methods of ordinary pre-stressed reinforcement in concrete beams and slabs, and mainly introduced the method and the calculation theory in superstructure reinforcing. Further, an example of T-type beam was given to present the cross section calculation of a reinforcing pole.
