根据现场监测资料，总结了青藏铁路沿线年平均地温不同的4个多年冻土区路基变形特征。然后，对几个典型的监测剖面进行了进一步的分析，讨论了这些路堤变形的机理，并考虑了详细的温度和地下条件。结果表明，在有MAGT的地区
Based on field monitoring datasets, characteristics of embankment deformation were summarized along the Qinghai-Tibet Railway in four permafrost regions with different mean annual ground temperatures (MAGTs). Then, further analyses were carried out at some typical monitoring profiles to discuss mechanisms of these embankment deformations with consideration of detailed information of thermal and subsurface conditions. The results indicated that in regions with MAGT
