Résumé: This work aims to present a numerical study using finite element analysis using the model of plane strain performed on sand with and without layers of géogrid charged with two closely spaced strip footings. The calculations are performed using the code Plaxis2D. The soil is represented by Hardening Soil Model and the reinforcement will be represented by elastic elements. A parametric study revealed the role of some parametric on the interfering factor (ζγ).The results showed that ζγ of the interfering reinforced footings is greater than ζγ of the unreinforced footings and the efficiency of reinforcement on the bearing capacity of interfering footings is greater than that on an isolated reinforced footing. In addition, reinforcement caused the bearing capacity of interfering footings to increase for one and two reinforcement layers, respectively.
