英文摘要	The results of studies of mountain permafrost of Alpine type by the methods of thermometry and geoelectrical survey are presented. The influence of natural and anthropogenic local factors on the structure of permafrost is demonstrated using the geoelectric models. Such factors include the exposition of the slope, the tectonics, the warming and cooling effects of the foundations of buildings. Changing slope exposure is expressed on geoelectric models by the decreasing of resistivity of high-resistance horizon, the violation of its continuity and the decreasing of its thickness. In the area of faults the discontinuous or island character of high-resistance horizon (permafrost) is observed. During the seismic events the temperature of rocks increases here up to the positive values. According to geophysical data, the formation of taliks occurs in the basis of deformed buildings, in the places of accumulation of snow at snow barriers and under the sites with asphalt covering.
