Abstract

Frozen soil is a kind of special type of soil; it’s sensitive to temperature and quite unstable. In seasonal permafrost region, the fluctuations of temperature will cause a large degree of influence on frozen heaving characteristics. This paper selects the highly frozen heave sensitive silty clay of the seasonal frozen soil region and does the frozen heaving characteristic test, in order to study of the occurrence of frozen shrinkage phenomenon and the frozen heaving characteristic of frozen shrinkage phenomenon. By the experimental study found that when the soil moisture content is low, the volume of water crystallizes into ice is not enough to fill the porosity of the soil body completely, cause the phenomenon of soil volume reduction. At the same time, the emergence of the phenomenon of frozen shrinking makes the soil temperature field a mutation, the soil moisture occurs crystallization in the case of soil inside moisture migration, frozen heave is negative, frozen heaving performance is relatively weak.
