The modern concept of the reinforced earth technique dates to the early 1960s. In the time this practice has been used and studied, it has enjoyed great popularity due to its relatively low costs compared to equivalent traditional systems, the degree of reliability of the system, its architectural appearance and diversity. In 2001, the United States Federal Highway Administration developed the MSE wall design and construction manual, currently FHWA-NHI-10-024 and FHWA-NHI-10-25, which provide instructions and recommendations for the design and construction of these structures, based on the instructions of the AASHTO LRFD standard. These sources include a series of assumptions, among which is the assumption of the base of the wall as an equivalent foundation. The AASHTO LRFD standard states it as follows: “(…) An equivalent footing shall be assumed whose length is the length of the wall, and whose width is the length of the reinforcement strip at the foundation level. Bearing pressures shall be computed using a uniform base pressure distribution over an effective width (B ’= L-2e)”. AASHTO LRFD (2010). The present research aims to analyze the way in which stresses are transferred to the foundation soil of a reinforced soil wall to verify in which way that assumption is technically correct. As well as to analyze the possibility of reducing the extension of the reinforcement used, by means of an optimization of the calculation through a model closer to reality. To do this, it is intended to carry out a Finite Element Analysis using a Constitutive Model that incorporates the non-linear behavior of the soil into the model, both for the filling material and for the foundation soil.
