| Popis: | The study is carried out into the stability of edges of open pits with a stratified structure. The angle of the strata slope and the ultimate elastic compressive and shear strengths are assigned. The maximal allowable depth of an open pit is determined depending upon the pit edge incline. The problem is solved from the constructed equations of plasticity of a stratified material. The limiting loads under which the plastic zone come onto the pit side surfaces and cause the pit slope stability loss are calculated. |
