摘　　要：对南京长江大桥南引桥双曲拱桥火灾后进行结构分析,采用了两阶段加固方案,经荷载试验证实了加固效果良好,可为同类工程加固提供有益的参考。The structural analysis was made for the two-way curved arch bridge of the south approach bridge of Nanjing Changjiang River Bridge after the arch bridge was hit by fire and the bridge was later strengthened by the two-stage strengthening schemes. The effect of the strengthening of the bridge proved to be sound through load tests and the strengthening may provide helpful reference for the strengthening of other similar bridge works.
