A Research on Methods to Improve the Subgrade Stability in Permafrost Regions

Abstract:

There are a lot of methods to improve the subgrade stability in permafrost regions. The scope of application and the advantages and disadvantages of the five methods including heat stick, insulation method, sunshade awning, particle improved method and ventiduct subgrade were analyzed. It can provide reference value for subgrade construction and diseases lot maintenance.
