For gravity retaining walls supporting cohesionless backfill, a limitation of the validity of Coulomb and Mononobe-Okabe methods for determining static and seismic static-equivalent active earth thrusts, is analysed. It is shown that beyond a certain inclination of the back of the retaining walls, those classic methods are not valid. In these cases a mechanism different from the one of the classical methods is formed. A simple methodology to determine the active earth thrusts depending on the inclination of the back of the retaining wall is presented.
