The finite element analysis model of roadbed temperature field in permafrost region is established with finite element software platform. By using this model, the temperature field of roadbed is compared and analysed, and the freezing-thawing depth and variation rule of roadbed are studied. The results showed that the actual freezing depth was 1.8m. With the increase of the climate warming temperature, the temperature field in the roadbed changes slowly, and the temperature at different depths increases. Due to the influence of climate warming, the roadbed was in a complete positive temperature state when the maximum freezing depth appeared after 20 years. The result shown that the time of the roadbed appeared in the maximum freezing depth was earlier, the time of the roadbed in the seasonal freezing area became shorter, and the maximum freezing depth decreased.
