The Construction of Transport Infrastructure on Permafrost Soils

The issues associated with freezing and thawing of soils in the subsoil of a complex of port facilities including transport infrastructure have been considered. The solution of thermal-physical problems of freezing, frost heave and thawing of soils has been made in spatial domain; the results of calculations are compared with the practical values. Numerical simulation of the problem of stability of structures on permafrost soils allowed predicting a possible soil thawing depth in time and optimizing the use of modern thermal insulation materials. The proposed calculation methods will provide reducing cost of development of transport infrastructure and port facilities under construction in the important northern regions of Russia.
