摘要
结合工程实例,介绍了拱上补强法加固双曲拱桥的施工方案,以增加主拱圈有效截面积并改善其结构受力,提出了膨胀混凝土的微膨胀原理及其在结构加固中的工程优势。
Combined with practical work the construction scheme of reinforcement method on arch ring of double curved arch bridge is introduced, which increase effective cross-sectional area of main arch to improve structural behavior; at the same time the expensive principal of expensive concrete as well as the advantages of its application in structural strengthening.
