研究目的:针对青藏铁路特殊的高原地质地理、水文条件、路基状况等,分析了青藏铁路路基病害发生的可能性和引起路基变形的多年冻土现象。研究结果:文章提出了多年冻土地区铁路的病害特点,同时根据高原多年冻土的特殊性,提出了相应的路基养护措施和养护工作的内容,并对一些路基病害提出了应急预案;最后就青藏高原多年冻土区铁路路基的养护措施提出了相关的建议。
Research purposes: In view of the geology, geography, hydrological conditions and subgrade conditions of the Qinghai-Tibet Railway, the possibility of subgrade defects and the permafrost causing deformation of subgrade are analyzed. Research results: The paper puts forward the characteristics of the railway in the permafrost region. At the same time, according to the peculiarity of the permafrost in the plateau, the corresponding subgrade maintenance measures and the conservation work are put forward, and some emergency plans are proposed for the subgrade diseases. Finally, Relevant suggestions are put forward for the conservation measures of railway subgrade in the permafrost region on the Qinghai-Tibet Plateau.
