Modeling of the Thermal Interaction of Sandy Fill and Frozen Base Soils

Аннотация

Numerical modeling of the thermal interaction of sandy fill and frozen base soils was performed in order to determine the role of natural and technogenic factors in the formation of the soil temperature regime for the Eastern-Messoyakh deposit. The heat-engineering calculations revealed a significant effect due to large snow accumulations and meltwater infiltration into the fill soil. The use of reference climatic indices in the calculations without taking account of the observed increase of air temperature causes the predictive models to deviate from the actual data.
