In this paper, a new model is presented for calculating the thermal conductivity of soils, and the main provisions for the derivation of analytical formulas are given. The presented model allows taking into account the density, moisture content and temperature of the soil base. The technique presented in the paper makes it possible to dispense with laborious experiments to estimate the thermal conductivity of the soil. The method of analytical calculation is step by step presented in the paper. Two variants of using the method are proposed:
1) Less accurate method, for preliminary evaluation, without the need to take probe and conduct experiments.
2) More accurate method, with at least one experiment with a disturbed or undisturbed sample.
The results of comparison of calculated values of thermal conductivity and experimental data are presented.
