The identification of the landslide preparation and development mechanisms is the key to the sustainable development of landslide and landslide-prone urban and mining areas. The understanding of the landslide preparation mechanism is necessary for landslide hazard and risk assessments and designing proper protection measures and monitoring. A new equation for calculation of a slip surface depth (of a landslide basis) was obtained, using slope morphological and soil strength parameters. A new elaborated approach fo...

The landslide cycle of development of deep-seated landslides begins when a new landslide block is being separated from the bedrock mass. It completes when this landslide block is displaced to the level of a landslide terrace, situated on the landslide slope. The initial stress state in the bedrock mass with horizontal earth surface (before the landslide block forms) is regulated by the Mohr-Coulomb criterion. The appearing of a landslide cirque as well as the sliding basis causes the change in the initial stress s...
