Analysis of volumetric unfrozen water contents in freezing soils
In this study, a series of freezing experiments were carried out to investigate the changes of volumetric unfrozen water contents in freezing soils. The experimental results show that the soil type and the initial volumetric water content have significant effect on the freezing point and volumetric unfrozen water content of freezing soils. On the base of the experimental results and the previous researches, a new model was developed to describe the changes of the volumetric unfrozen water contents in freezing soils. The developed model was validated by comparing the calculated results against the experimental ones.
