Soil slopes are structures that apply in many cases such as roads, rail ways and many others. These structures need to be reinforced in the case of low-resistance ground, loading on a slope or geometric properties such as very steep or high slope. One of the methods for analyzing the behavior and providing appropriate model for designing the slopes is the Schmertmann method. In this method ,the influence of reinforcement in the vicinity of sliding surface is considered so that the vertical component of reinforcement force increase the vertical forces on the slip surface ,thus increasing the shear strength .but pulling out the reinforcement during mass movement and interaction between soil and geotextile and the vertical component of resultant shear stress between them can decrease the resistance forces perpendicular to the slip surface and so the safety factor of the slope. In order to verify the accuracy of the problem, this study is performed using ABAQUS software based on the finite element method .seen as a result that interaction between soil and geotextile has little effect on reducing the resisting force and the factor of safety of slope.
