Abstract Research purposes: Aiming at the Qinghai-Tibet railway's special plateau geology, geography and hydrologic condition, subgrade state and so on, this paper analyses the possibility of the Qinghai-Tibet railway occurring subgrade disease and the permafrost phenomena which can cause subgrade anamorphosis.
Research results: The paper extractes the characteristics of the railway disease in permafrost region. And according to the particularity of the plateau permafrost, the paper extractes corresponding subgrade maintaining measure and maintenance contents. Considering the peculiarity of the plateau permafrost, we put forward emergency measures for some subgrade diseases. At last, the paper advances corresponding suggestions about the railway subgrade's conserving measures of the Qinghai-Tibet plateau permafrost region.
