Capacité portante ultime d'un sol renforcé par une tranchée

Bouassida, Mounir / Jellali, Belgacem

This contribution deals with the ultimate bearing capacity determination for a rigid foundation resting on a soil reinforced by a trench. The soil and the reinforcing material, being homogeneous and isotropic, are characterized by a plane strain Coulomb's strength criterion with respective cohesion, friction angle and unit weight C₂, γ₂ ø₂ and C₁, γ₂, ø₁. Based on the kinematic approach of yield design theory, using Prandtl's mechanism an upper bound of the ultimate bearing capacity is established analytically for all reinforcement cases. Therefore, the mechanical characteristics of the trench material are identified from which the reinforcement occurs.
