	This work presents a numerical analysis of the dynamic behavior of reinforcements of liquefiable loose sand by flexible columns (stone columns) and Mixed Module Columns (CMM). In this study, the numerical simulation was carried out in 3D difference element analysis. Using a Finn model for dynamic Pore-Pressure Generation and the foundation subjected to the variable-amplitude harmonic ground motion of the Boumerdes earthquake (2003). When the height of the rigid part of the CMM has 50\% of the column, the behavior of the improvement soil is the same by stone columns under the foundation, also the increase in the rigid part decreases the settlement. Overall, the high recorded accelerations by CMM indicate the largely preservation of the foundation stiffness
