Water migration is the key contributor for frost heave during soil freezing, and the driving force of water migration depends on soil temperature, unfrozen water content, matric suction and the relationship between them. The relationship is known as the soil-water characteristics in frozen soils. Generally speaking, the soil-water characteristics and the hysteresis effects have similar change laws between drying-wetting and freezing-thawing processes. It seems that the soil-water characteristics in frozen soils can also be explained based on the existing theories on soil-water characteristics in unfrozen soils. However, there are several special factors cannot be ignored, such as negative temperature, phase change and so on during freezing and thawing process. Therefore, it is believed that although the soil-water characteristics and the hysteresis effects are similar, their mechanisms may be quite different. Therefore, a great deal of work need to be done to develop the soil-water characteristics during soil freezing and thawing. Detailed analysis and summary are provided about the present situation and the existing problems of the water characteristics during soil freezing and thawing, as well as references for the aftertime study are put forward: a) establishing a typical model to the soil below freezing point to predict soil-water characteristics effectively with limited data; b) investigating the similarity and difference of the soil-water characteristics effect between unfrozen and frozen soil, and demonstrating the mechanism of the hysteresis effect during freezing and thawing; c) promoting the research of measurement techniques of the soil-water characteristics in frozen soil.

Key words: freezing-thawing process, soil-water characteristics, unfrozen water content, matric potential, hysteresis effect
