Simulative analysis on heat stability of embankment in high temperature permafrost district of eastern Tibetan Plateau

The heat stability of embankment in the high temperature permafrost regions of the eastern Tibetan Plateau was simulated,and the heights of embankment were discussed and figured out,respectively for asphalt-paved,concrete and gravel road surface,according to the natural geographic and geologic conditions in the high temperature permafrost regions of the district.The calculated results were in good agreement with the field data of the Qinghai-Xizang Highway.
