Characteristics of frost heaving were observed for the soil filled with in the natural soil bath.
From this study, the following conclusions were drawn.
1. The frozen thickness for soil was thought to be a constant.
2. The amount of ground frost heave increased in line with an increase of the temperature gradient.
3. In cold region, the effect of the tapered pile was low.
4. The amount of ground frost heave coincided with the amount of wate migration at the freezing front.
5. In the case of ice lens near the ground surface, the effect of a sublimation was small.
6. The pressure action on structure was a great difference with the shape of underground object.
