A multiphase model is proposed for the elastoplastic analysis and design of soil structures reinforced by stiff linear inclusions, where shear and bending effects should be taken into account. A f.e.m-based numerical tool, incorporating a plasticity algorithm adapted to this multiphase model, is developed and illustrated on the example of a slope stabilized by such reinforcing inclusions. Emphasis is put in this analysis on the crucial role played by the shear and flexural behaviour of the inclusions in the slope stabilization.
