Experimental modelling of soil thawing

Abstract

Based on the modified solution of Stefan task for phase transition in a soil prototype in the form of half-space, an algorithm of calculating temperature distribution over time and soil depth, proposed by the authors, is substantiated. The data on the temperature at a particular location of the Taymyr Peninsula taken in summer 2011 are used for the purpose. Staring from 0 a. m. (local time) on July, 1st, every ten days of the period under consideration the temperature values for the soil surface and the soli at the depth of 0.6 and 0.9 m were taken for the analysis. Numerical modelling as well as quantity and quality analysis for temperature stratification over time and soli depth have been made on the basis of the algorithm developed. The proposed calculation technique, based on modern information technologies, is of great practical perspective.
