In this study, slopes' stability was examined by soil deep mixing method with parametric analyses. To perform the required analyses, the finite element numerical method and PLAXIS software were used, and then the results of this method were compared with the results of limit equilibrium method obtained from Slope/w software. These parameters include the effect of the location of the first row of deep mixing columns along slope foundation, area replacement ratio along foundation slope, length, diameter, coefficient of cohesion, distance between deep mixing columns, position of the water level in the foundation, as well as the effect of the surcharge load. According to the obtained results of the analyzed model with both finite element and limit equilibrium methods, the factor of safety of slope stability constantly increases upon the increase of parameters such as amounts of area replacement ratio, diameter, materials viscosity (cohesion of soil deep mixing materials), length of deep mixing columns, and depth of groundwater level to the level of slope foundation.
