摘要
首先对国内外后张法预应力混凝土桥梁腐蚀现状进行了综述,重点讨论并分析耐久性失效的原因,提出保障耐久性的各种措施,并对目前国内外比较适用的无损检测技术以及已采用的监测系统予以介绍。通过分析比较,得出目前我国后张法预应力混凝土桥梁耐久性方面还存在的问题,并对以后的研究工作提出一些建议。
This paper described the research status on durability of post-tensioned concrete both at home bridges domestic and abroad.It analysed the reasons of corrosions of bridges and works out some available measures for durability.To improve the durability of bridges,it was important on design,construction,and maintenance.It also introduced some techniques of non-destructive test and monitoring systems which had better applicability.It also puts forward some suggestions on the problems of durability of post-tensioned eoncrete bridges in the future.
