Summary

The paper deals with actual changes of thermal properties of soils caused by freezing and melting and a method for calculating the thermal conductivity of frozen and unfrozen soils. The amount of unfrozen water in five kinds of soils was measured by the pulsed nuclear magnetic resonance method. Thermal conductivities of frozen soil were greater than those of unfrozen soil. Evaluated thermal conductivities generally corresponded well to measured values for the five kinds of soils.
