ABSTRACT
In this paper mapped 3D-infinite elements and 3D-finite elements are used for solution the structures on undeground. The static analysis of a structure-soil system supported by homogenous elasto-plastic soil is formulated. Near field is modeled by finite elements and far field by infinite elements. Stress-strain relationship is formulated for nonassociated plasticity theory. Drucker-Prager, Mohr-Coulomb and Hoek-Brown yield criterion describe well the elasto-plastic soil.
