The article deals with the problem of assessing temperature regime at various depths of Earth’s crust, the measurement of which by direct methods is impossible, and known indirect methods are dif-ficult to be implemented. The aim of the work is to construct a mathematical model of lithosphere tem-perature regime, the solutions of which made it possible to quantify stresses and displacements formed in geological environment due to a complex impact of tectonic and thermal processes on it. The results of quantitative estimates of thermoelastic deformations in surface layers of Earth's crust in relation to Arctic cryolithozone of Russian Federation are presented. Based on simulation results, temperature distribution fields are constructed, numerical estimates of displacements and thermoelastic defor-mations in surface layers of Earth's crust are performed both for the whole of southern Yakutia and for the vicinity of Yakutsk. An important conclusion is made that the presented models make it possi-ble, on a fundamentally new technological basis, to monitor buildings, engineering structures and their ground bases including cryolithozone conditions, to develop sound recommendations on the conditions of safe construction of both individual objects and their complexes, as well as to control a construction procedure on the territories of different size.
Key words: Arctic, cryolithozone, modeling, geological environment, temperature regime, thermoelastic deformations, monitoring.
