FORECAST OF FAILURE FORMATION ON COATED KARST SECTIONS
To assess the karst hazard of the areas covered by karst, the most urgent and complex problem is the local forecast of failure formation. With the development of karst under non-karst rocks, when reaching the critical dimensions of closed karst cavities, subsidence and dips occur on the surface. When the type of karst is covered, often funnels, dips or subsidence are absent or very weakly expressed in the relief, so it is impossible to assess the karst hazard without a large amount of drilling work. There are three known mechanisms of soil deformation above the cavity: landslide, suffusion, landslide-suffusion. The prevalence of one or another mechanism during the seasons of the year may vary. The methods of calculating the possible formation of surface failure karst forms under conditions of covered karst are considered.
