- Аннотация: The article presents the peculiarities of geotechnical and geophysical survey conducted in one of the High North areas. Based on the obtained site-specific geotechnical and geophysical data, the quantitative assessment was performed of slope stability. Soil slips occur on the site under analysis mainly due to significant terrain energy; low strength properties of soil due to moisture and thawing; and man-induced load. The high probability of landslide developments makes it necessary to cover the site with engineering protection. A simulation model was developed of the stressed-deformed state of the soil body using the finite-element technique. The calculations enable a conclusion that there are two stress distribu-tion patterns and, consequently, two deformation patterns on the site under analysis. The mathematical modeling conducted for the pressure distribution region is indicative of the likelihood for landslide defor-mations and profound soil subsidence to occur due to thawing (and, consequently, reduced modulus of deformation) in lenses and interstratified layers composed of icy grounds.
