摘要

•The theory of premelting in the presence of impurities in soils is developed.•A model to predict the variation of unfrozen water content is established.•Equivalent grain size is introduced to soils to calculate unfrozen water content.•The thickness of water film is mainly determined by the impurity concentration.
