PhD Andrey Kazeev, Dr. German Postoev, Ksenia Fedotova
The identification of the landslide mechanism of preparation and development is the key to the sustainable development of landslide and landslide-prone urban and mining territories. The understanding of the mechanism of preparation of a landslide is necessary for landslide hazard and risk assessments.
The mechanism and regularities of the formation of deep block landslides are considered.
The equation for the calculation of a landslide slip surface depth was obtained, using slope morphological and soil strength parameters. This equation can be implemented for deep landslides, occurring in different engineering geological conditions, from soils (weak loams) to rocks (calcareous clays, limestone).
A scientific explanation of effective reinforcement of territories with deep block-type landslides is provided.
The suggested protection strategy for sustainable development of slope territories bases on theoretical solutions of preparing of a destructive phase of landslide deformations, on taking into account mechanism peculiarities of deep block-type landslides, and also on investigation experience of such landslides in different engineering-geological conditions. New protection technologies for territories with deep-seated landslides of compression-extrusion type are considered in the article.
