摘要
文章根据青藏铁路多年冻土地区路基养护的特点,分析了路基病害主要是由冻胀引起的路基整体性破坏和融沉引起的滑塌,提出了冻土地区路基日常养护和大中修的工作内容,对多年冻土地区铁路路基的养护施工有一定的借鉴作用。
The characteres of roadbed disease on permafrost regions of Qinghai-Tibet are analysed. The roadbed integrity destroyed by frost heaving and slump for thaw collapse are the main causationes for railway roadbed disease on permafrost regions. The work content of ordinary maintenance and heavy repair for railway roadbed on permafrost regions are presented.
