Activization of geocryological processes, induced by changing of mean annual temperature has a significant influence on changing of climate parameters of geosystem lithogenic basis.
The methodology has been suggested for regional estimation of mechanical properties of saline frozen soils for different scenarios of climate changing. It has been based on complex analysis of mapping data, modelling of climate dynamics and data of saline soil mechanical properties.
The obtained results may be used for estimation of changing stability of nature-technical systems and, in particular, of engineering constructions foundations when ground temperature fluctuates due to climate changing or breaking of surface conditions.
