What determines the stability of embankment and separating dams?
The stability of the embankment and separating dams of a TSF is determined by a complex of geotechnical, hydrogeological, and anthropogenic factors. The following have the greatest influence: physical and mechanical characteristics of soils and tailings (wastes); the process of construction and operation of a structure; nature of its base; hydrodynamic, hydrostatic, seismic, and dynamic forces. A structure option of the dam body at this specific section, developed on the basis of the simulation, provided a factor of safety values for the outer slope at well no. 324-19. This was FoS = 1.664 for the main combination of loads, and FoS = 1.430 for a special combination of loads under seismic action.
