ABSTRACT
The theoretical bases of the space slope stability analysis and the example of its implementation are presented. The plane slope stability analyses are usually used in practice and are suitable chiefly for analyses of slopes that are uniform in the direction perpendicular to the treated profile and whose the loads are uniformly distributed in that direction. When slopes have no uniformly layered soils, local loading or unloading, more complex procedures of the space stability analysis are needed to reach more real results. The energy or kinematical method (KEM) is used in the presented paper.
The considered problem is exacting, so some simplifications are considered: the peak shear strength of the soil, blocks are completely rigid, only associative soils and translator types of the failure are treated, no potential energy dissipation on the vertical surfaces, and the Mohr-Coulomb’s yield criteria is assumed.
