Abstract
Purpose of the work has been to assess the natural and anthropogenic factors’ influence on landslides formation and development at the north-western Black Sea coast, as well as to identify regularities in deformation processes dynamics after landslide prevention works implementation. Methodology. The data of long-term (1950–2020) instrumental observation performed by many organisations at different sites of the north-western Black Sea coast have been used to identify the regularities in landslide formation and development and the dynamics of landslide slopes deformation processes. Results. It has been established that rocks deformation and slopes dynamics are caused by combination and interrelation of exogenous processes of gravitative nature, reological properties of rock, tectonic differentiated movements of micro- blocks as the result of quasi-periodical changes in stressed-deformed state of rock massif due to rotational and tidal forces. Conclusions. Regularities and tendencies of long-term engineering & geodynamic state of landslide slopes after prevention works performing have been identified. Making assessment of prevention works’ engineering & geological effectiveness and forecasts of the slopes long-term stability one should take into consideration spatial and temporal variability of engineering & geodynamical conditions and high sensitivity of landslide slopes to a wide spectrum of natural and technogenic factors.
