摘要
广西百色澄碧河和永乐大桥 ,原设计为汽 -2 0 ,挂 -1 0 0刚架拱桥 ,后因年久失修有病害 ,多处发生裂纹。现为运输总重 42 5 2kN的超大构件的需要 ,应用粘钢加固技术对其进行了补强 ,使桥梁承载力大幅度提高。重点介绍粘钢加固设计、粘钢加固方案及施工工艺。
Chengbi River Bridge and Yongle Bridge, originally designed as rigid framed bridges for truck load 20 and trailer load 100 tons, are now in defective conditions with a lot of crackings. In need of transporting oversized and heavy members (with total weight of 4 252 kN), the strengthening technology with bonded stecl plates are used to enhance their carrying capacity to large extent. This paper mainly introduce the design and constraction technology of the bonded steel strengthening method.
