Abstract
For the first asphalt and wide embankment which build in Qinghai Tibet plateau, this paper considers the temperature boundary condition of the roadbed the Vehicle load and the global warming, to analyze the temperature field distribution and subgrade deformation of the different traits road. The numerical results show that, the vertical displacement of asphalt pavement is deeper than cement pavement, and compared to asphalt pavement, the thawing core under cement pavement subgrade disappeared about 3 months earlier. It shows that compared with asphalt pavement, cement pavement can protect permafrost under subgrade.
