The characteristics analysis on frost heaving of subgrade in the seasonally frozen ground region

DU Zhao-cheng

Abstract

The thawing settlement and frost heaving may bring the serious damage on the subgrade engineering in the seasonally frozen region.On the basis of the data of subgrade frost heaving observation in Chang-Yu freeway from 2000 to 2002 years,this paper analyzes the factors of temperature,water,soil and subgrade type which influence the subgrade frost heaving.
