The article considered the process of global warming, which is
mostly represented in the northern territories of Eastern Siberia. A growth
of snowfall gradient and wind load gradient, resulting in building up of
snowy thermal insulation layer, which prevents ground freezing, is analyzed.
According to the preliminary calculations the forecast of thawing of the permafrost will completely degrade in the second part of the 21st century.
The increase of the temperature and the strength of the active layer lead to
the building and structures deformation. Together with natural factors technogenic and anthropogenic factors have a great impact: effect from building
operation, improper handling of pile-foundation (restricted ventilation of
crawlway, no provided runoff), destruction of networks. The simulation
model of climate fluctuation influence on thawing of the permafrost was developed. The melting process or correspondingly crystallization takes place
during thawing/freezing of the permafrost.
