大跨径钢管混凝土拱桥管养系统研究

Research Of Care And Maintenance System For Long-span Concrete-filled Steel Tubular Arch Bridges

近年来,随着钢管混凝土拱桥在我国的大量建成与投入使用,一些桥梁已经暴露出后期使用与养护上的一些问题。本文结合工程实例,根据桥梁所处工程地理环境、钢管混凝土拱桥各个构件的受力特点等要素对该类型桥梁的后期管养系统提出几点建议。

In recent years, as concrete-filled steel tube arch bridges being built and put into use, maintenance and latter period using problems of some bridges happens. This paper combine engineering example to put forward some suggestions about this kind of bridges＇ latter period management and maintenance systems according to some elements such as engineering geographical environment which the bridges located, each component＇ s stress characteristics of the concrete-filled steel tube arch bridge.
