This paper describes the formulation of a finite element method by which a limit analysis of a rigid–plastic medium with discontinuities can be performed. The Drucker–Prager criterion is adopted to describe the yielding of the medium, while the Mohr–Coulomb law is used to model the interface of the discontinuous velocity fields. Both associated and nonassociated flow rules are considered in the constitutive characterization. Results are presented to illustrate the influence of discontinuities on the bearing capacity of a surface foundation. Key words: bearing capacity, constitutive law, dilatancy, discontinuity, limit, plasticity, finite element analysis.
