Abstract：Influenced by the regional climate and external environment conditions, the typical embankments in permafrost regions along the Qinghai-Tibet Railway have specific characteristics in terms of thermal stability and engineering stability. In consideration of the climate and environment conditions in permafrost regions, the embankment sections of the Qinghai-Tibet Railway from Golmud to northern Lhasa are selected as experimental samples. The stress-strain field and deformation of embankments under the action of temperature field coupled with the dynamic field generated by train load in permafrost regions along the Qinghai-Tibet Railway are simulated. Finally, the engineering measures to control the deformation of the embankments in permafrost regions are evaluated.
