摘　　要：随着桥梁运营年限的增加,大量在役桥梁承载能力评估成为现有桥梁管养工作的重要组成部分。阐述旧桥承载力评估的内容和方法,并结合工程实例通过外观检测、结构检算及静载试验分析某钢筋混凝土旧桥的承载能力,同时采用有限元法分析该桥在静载试验过程中的应力及变形。结果表明,该桥安全储备不足,构件劣化的趋势较快。综合考虑其它因素,建议拆除重建该桥,并给出新桥设计的建议。As the operation years of a large number of in-service bridges increase,the assessment of carrying capacity of these bridges has become an important component of current bridge management and maintenance.In this paper,the contents and methods of assessment of the carrying capacity of old bridges are expounded.With reference to the practical bridge examples and through the visual inspection,structure checking calculation and static load tests,the carrying capacity of an old reinforced concrete bridge is anal...
