摘要
通过对国内外多种旧桥承载力评定方法的分析、研究，提出了以应力释放法为主的综合评定方法，并用它检测了广州海珠大桥的主要杆件的实际应力，与理论计算值对比，得到广州海珠大桥承载力评定结果。
In this paper, some evaluation methods of bearing capacity of old bridges in the world are analysed and studied, and the stress release method is presented, the stress of Guangzhou Haizhu steel bridge is analssed using this method, compared with the theoretical value, the result of the bearing capacity is obtained.
