摘　　要：随着中国市政基础设施建设的飞速发展,城市桥梁遭受火灾的现象逐渐增多。桥梁遭受火灾后,其承载能力、使用性能和运营安全将受严重影响。以生米大桥西岸引桥火灾为例,对其灾后结构进行分析计算,制订了科学、合理的维修加固方案。荷载试验表明,该桥维修加固效果良好,其方案可为同类工程维修加固提供有益参考。With the rapid development of infrastructure construction in China, the cases of city bridge sub？jects to fire gradually increase. After fire, the carrying capacity, performance and operation safety of bridge will be seriously affected. In case of a fire in the west bank approach bridge of Shengmi Bridge, the structure of post disaster is calculated and analyzed in this article, and a scientific and reasonable repair scheme is proposed. Load test results show that the scheme can get good effect and can provide reference for other similar projects.
