摘要
阐述了钢箱梁的疲劳检测内容和钢箱梁的裂纹的修补流程,分析了钢箱梁的各主要构件的检查周期。分析了钢箱梁钢桥面板易于产生疲劳损伤的关键位置。根据采取的维护措施以及措施的紧迫性,提出了钢箱梁疲劳评估的判断项目,将判断项目分为5个级别,便于疲劳评估。
The fatigue detection and crack repair of steel box girder were described.The detection cycle of main components of steel box girder was analyzed.The key parts of steel deck which were easy to have fatigue damage were analyzed.According to the measurements and its urgency,the judgment items which have 5 levels were put forward in order to evaluate fatigue.
