近年来,桥梁垮塌事故越发频繁,桥梁安全性与耐久性问题已成为当前我国桥梁建设急需解决的重要问题。结合多年工作经验,本文阐述了近期我国桥梁结构的安全耐久性概况,分析了安全耐久性较差桥梁结构的主要原因,指出了桥梁安全耐久性设计与施工中存在的问题,总结经验教训,最后提出了重视疲劳损伤、超载问题及借鉴国外先进经验成果等提高安全耐久性的对策及建议,为今后桥梁工程的设计与施工提供参考。
In recent years, the accident of bridge collapse has become more and more frequent. The problem of bridge safety and durability has become an urgent problem to be solved urgently in our country’s bridge construction. Combined with years of work experience, this article describes the recent overview of the safety and durability of the bridge structure in China, analyzes the main reasons for the poor durability and safety of the bridge structure, points out the problems in the design and construction of the safety and durability of the bridge, summarizes the experiences and lessons, and finally The countermeasures and suggestions to improve the safety and durability of the bridge engineering are put forward by paying attention to the problems of fatigue damage, overloading and using advanced experience from other countries for reference.
