Reinforced earth in plane strains is idealized as a homogeneous material with the strips attached to the elastic soil matrix by a conceptual shear zone. A "no-slip" finite element model is derived by assigning a large shear modulus to the shear zone. Relaxation of this modulus using a tangential stiffness algorithm in conjunction with a mohr-coulomb strip-slip criterion allows slipping to be simulated. The finite element formulation is validated and the finite element discretization assessed by comparisons against exact solutions for a simple test problem. An idealized reinforced earth wall example is used to demonstrate the feasibility of the method and to answer the question: "is slipping significant?" the method is shown to be potentially useful, and slipping is shown to be significant. /Author/TRRL/
