摘要:
文章以哈尔滨市内一座铁路框架桥事故为研究对象，介绍了烧损桥梁的混凝土抗压强度试验、碳化深度检测、钢筋拉伸试验、静动载试验等各项研究内容。根据各类试验结果，判断出桥梁结构碳化等级和混凝土损坏等级，综合评估确定烧损桥梁可修复使用，最后提出了修复建议。文章可为同类型发生火灾桥梁的检测加固提供参考。
Abstract:
Based on an example of a railway frame bridge accident in Harbin, various research projects of the burned bridge such as concrete compressive strength tests, carbonization depth detection, steel tensile tests, static and dynamic tests are introduced in the paper. According to the various tests results, the carbonization grade and concrete damage level of the burned bridgeare concluded. The burned bridge can be repaired and continued to be used through comprehensive assessment. Finally, the restoration suggestions are put forward. This paper has certain reference value for the detection and reinforcement of other burned bridges with the same type.
