Abstract: In this work, three-dimensional finite, element, analysis of single, floating reinforced, stone, column, (FRSC) and, pile foundation under axial load analyzed using PLAXIS (3D) 2013. The hardening soil and Mohr-Coulomb models are used to simulate the behaviour of clayey soil and FRSC respectively. While linear elastic model is used to simulate the behaviour of structures (pile, footing and geo-grid). Two types of pile foundation are studied, bored and driven concrete pile, the parametric study including the changing of length and diameter of (FRSC) and bored pile, however, the driven pile has constant cross section (28 x 28) mm. For FRSC and bored pile two lengths (6 and 12) m and three diameters (0.4, 0.6 and 0.8) m are analyzed. From the results of finite element analysis, the bored pile has clear advantage of improvement over the driven pile and FRSC, the results of the improvement using the FRSC were better than the driven pile.
