桥梁结构安全性与耐久性的现状分析

On Current Condition Analysis of Bridge Structure Safety&Durability

近年来,桥梁垮塌事故越来越频繁。桥梁安全性与耐久性问题已成为当前我国桥梁建设十分迫切需要解决的问题。根据多年工作实践,阐述了现阶段我国桥梁结构安全性与耐久性概况,结合一些桥梁垮塌事故,分析总结了桥梁结构安全性低与耐久性差的主要原因及经验教训。最后提出了提高桥梁结构安全性与耐久性的对策和建议。

Bridge collapse accidents have appeared increasingly in recent years.It has become an urgent issue of bridge safety and durability for bridge construction in current China.According to experience of several years,the current stage condition of bridge structure safety and durability has been put forward in this paper.Combined with some collapse accidents,the main reasons and lessons of low safety and bad durability have been analyzed and summarized,and moreover,several countermeasures and suggestions are proposed to solve this problem.
