Reinforced earth is a composite material made up of soil layers and steel strips placed on each other. Mechanical characterization of this material can be achieved by two conventional methods: one is the theory of plasticity, the other is the theory of elasticity. Accordingly, the structural design methods can be classified as bearing capacity oriented and as deformation specifications oriented. Bearing capacity is calculated from the known plastic behaviour of the reinforced earth, while the deformation or strain of the reinforced earth retaining walls and slabs can be calculated from the elastic properties of the material. Estimation of the elastic constants requires the knowledge of the elastic parameters of the soil and steel, and the geometry of the reinforcement. From the constants of the transversally anisotropic material the tilting of the reinforced earth wall and the settlement of the reinforced earth slabs are computable. /Author/TRRL/
