Calculation of Thermal Conductivity of Fine Soils Taking into Account the Quantity of Unfrozen Water

To generalize experimental data on the thermophysical characteristics of soils at positive and negative temperatures and reduce the scope of the experimental work, there is a need to systematize and expand the calculation of the thermal conductivity of soils. This paper proposes a method for calculating the thermal conductivity of fine soils in frozen and thawed states. The calculation models include a shell model combined with a model with interpenetrating components. The calculated thermal conductivity values were compared with experimental data.
