Interface effects have an essential role during any contact between two bodies; and the inclusion of contact-friction in the model body can be a useful approach. This is the case, for example, of adding the recent depot on a former layer. The practical applications are either geology or geodynamics, the modeling of waste storages and the stability analysis of artificial embankments. The latter is examined in this paper, as we use the interaction of contact friction between two blocks (bodies). This study was carried out using the finite element method coupled with the shear strength reduction technique. The results of this study indicate that we must take into consideration any rupture in slopes because this helps to know the real situation after analyzing the slope and also to show the importance of the presence of interaction interfaces in modeling the frictional contact between soil interfaces. Young's interface modulus plays a very important role in the interaction.
