摘要
设置钢轨伸缩调节器是解决桥梁结构与钢轨变化不一致的主要方法。文章结合京沪高速南京大胜关大桥工程,全面系统地分析国内外高速铁路钢轨伸缩调节器的主要类型,并对300km/h SA60-1200(B)型钢轨伸缩调节器的日常养护及遇到的问题进行探讨,供类似工程参考。
To solve the incoordination change between bridge structure and steel rail, setting expansion joint is the main method. Combining with Dashengguan Yangtze river bridge engineering of Jinghu high-speed railway in Nanjing, this paper introduces expansion joint types of high-speed railway at home and abroad comprehensively and systematically, analyzes daily maintenance and problems of expansion joint 300km/h SA60-1200（B） which could be taken as reference for similar engineering.
