In the last 30 years, many studies have been done concerning the stability analysis of soil structures and determination of their deformations. Finite element method, is a powerful tool for investigation in this field. Elasto- perfectly-plastic constitutive law and associated flow rule, along with finite element method are utilized for calculating the safety factor of soil slopes. Several failure criteria have been presented. In this paper, nine failure criteria are used for stability analysis of soil structures. The results are compared with Bishop Method
