青藏铁路适应气候变化的筑路工程技术
The climate warming,which has an evident effect on the warm/ice-rich permafrost,should be considered in the engineering design of the Qinghai-Tibet Railway in permafrost areas.Based on the rule mentioned above,many design ideas and measures such as cooling embankment and controling of heat conduction,radiation and convection were proposed during the construction of the Qinghai-Tibet Railway to reduce the permafrost temperature and to reduce the impact of climate warming on the railway.These measures ensure the stability of the railway embankment in permafrost regions.
