ABSTRACT
This article presents the different calculation methods for active and passive earth pressures, and associated displacements, modified according to the recently published Eurocode 7 rules. Importantly, this article follows upon the C244, which deals more precisely with strengths of retaining walls and structures

INTRODUCTION
The purpose of this article is to determine the thrust and abutment forces as a function of the geometry of the screens or retaining wall and the soil mass selected, the mechanical characteristics of the soil and the relative displacements of the wall with respect to the soil.
The article presents the thrust and stop coefficients, their calculation methods (Mohr-Coulomb, Rankine, and limit equilibria) and compares them.
These methods are developed for different types of soil (coherent or powdery), with calculation examples.
