At present, there is a large amount of experimental material on the thermophysical characteristics of typical soils in dry and wet conditions at hot and cold temperatures. To generalize these data and to reduce the volume of experimental work carried out, it is necessary to systematize and expand the work on the calculated determination of the thermal conductivity of soils. A method is proposed for calculating the thermal conductivity of finely dispersed soils in frozen and thawed states. A shell model and a model with interpenetrating components are used as design models of thermal conductivity for finely dispersed soils. An approximation of the volumetric heat capacity dependence on temperature was obtained experimentally and the amount of unfrozen water was calculated to take into account the temperature dependence of the thermal conductivity of finely dispersed soil.
