ABSTRACT
Due to less shear strength and high compressibility of soft soils, construction of soil embankment on these types of soils leads to problems such as big and non-uniform settlements. Nowadays, soil reinforcement is used as a trustable and efficient way for increasing soil strength and stability of it. Usage of geosynthetics for increasing height of embankments and their stability has been increased significantly in recent years. Using geosynthetics cause decrease of tensile weaknesses and make the soil more stable by decreasing the settlement of it. Inthe present study,the effect of axial stiffness of geosynthetics, the number of layers, and the angle of slope on embankment manner were analysed on a clayey layer of soil by the use of Plaxis 2D which is a finite element software. The results showed that using geosyntheticsled to a decrease of deformations and increasing of stability of embankment. At the same time,decreasing embankment slope and increasing stiffness caused decrease of deformations.
