Abstract
The dimensioning of a retaining structure consists in determining the geometric and structural elements so that it is stable under the action of the forces applied to it and in particular of the passive and active earth pressure. The stability of these structures is often ensured by anchors placed in the soil. The anchor plates are largely based on passive earth pressure to resist to the ultimate pullout capacity. This study focuses on a numerical study using the software PLAXIS 3D Tunnel, to evaluate the ultimate pullout capacity of vertical square anchors plate embedded in a frictional soil. The soil was considered to be a linearly elastic-perfectly plastic material, obeying Mohr–Coulomb criterion. The variation of the ultimate pullout force was calculated as a function of the variation of the anchor depth. The anchor break-out factors were estimated for a rigid and rough vertical plate, subjected to horizontal loads. The results have been compared with those available in the literature.
