    A retaining wall is a wall whose role is to retain the soil through its embedding in the ground and / or anchors. For their sizing, they are statically considered as a beam on support. The wall must be dimensioned in order to avoid limit states of bearing capacity (Ultimate or rupture) in the ground (exceeding shear strengths) and in the structure (exceeding of material strengths) as well as service limit states (horizontal displacements, settlements). The distribution of earth pressures on unanchored retaining walls is calculated according to the classical theory of Coulomb; it varies linearly with depth. The presence of anchorages (number, position) greatly influences the greatness and distribution of earth pressures, behind the anchored walls; this is why we apply approximate distributions for the active thrust.

      The objective of this thesis is to propose earth pressure distribution diagrams on anchored retaining walls which better reflect real cases by taking into consideration all the boundary conditions (type of soil, type of wall, overloads, position and number of anchors, wall and earth movements behind and in front of the wall).
