Stability of embankments in permafrost regions considering temperature field coupled with dynamic field

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.
