YIELD DESIGN OF REINFORCED EARTH WALLS BY A HOMOGENIZATION METHOD

The method presented here originates from the idea that, from a macroscopic point of view, reinforced earth can be regarded as a homogeneous material with anisotropic properties, owing to the existence of privileged orientations due to the reinforcing strips. The strength criterion of such an equivalent material, which can be determined theoretically starting from the strength data of the reinforced earth components, turns out to be of the anisotropic frictional type. This criterion is applied to the stability analysis of a reinforced earth wall, making use of the yield design kinematic approach with rigid block failure mechanisms. The theoretical estimates obtained for the collapse height of the wall through this method appear to be in better agreement with experimental results than the values derived from classical design methods. Despite some limitations outlined in this paper, the proposed yield design homogenization procedure may become an appropriate design method for reinforced soil strtuctures in general.
