摘要
针对我国钢箱梁疲劳开裂维护问题,回顾国内外钢箱梁疲劳研究情况及进展,分析疲劳开裂特征,并围绕疲劳开裂的检测、评估和修复问题,阐述钢箱梁疲劳开裂维护研究中的主要关键技术以及相关结论,分析总结研究中存在的难点与热点问题,并对钢箱梁疲劳开裂维护研究发展进行展望和建议。
Based on the fatigue cracking maintenance for steel box girder, the paper provided a review on the research status at home and abroad. The fatigue craeking characteristics were analyzed. Some critical techniques, such as the detecting method, fatigue evaluation and repairing were illustrated, and some relevant conclusions about fatigue cracking maintenance at steel box girder were provided. The difficulties and pressing issues in the research were also analyzed. Finally, expectations and suggestions for fatigue research on steel box girder were put forward.
