“…Stone columns were first used in France in 1830, and they are widely used in other countries since 1950. In Iran at first it was used by the Ramming method, and since 2004 vibration technique was used in building stone columns (Etezad, M., et al, 2005), (Hughes, J.M.O and withers, N.J, 1974). In 1974 behavior of stone columns was studied for the first time.…”

In the present paper, the numerical analysis of stone columns in improving the bearing capacity of footing with the length of 10m, and thickness of 0.5 m in fine-grained soil is studied. The case study, stone columns group, has 3 columns which are symmetric. Two-dimensional finite element method is used for investigating the behavior of stone columns. In addition, behavior of stone column's materials and its surrounding soil has been modeled using the Mohr-Coulomb elasto-plastic constitutive model. In this analysis, the various parameters such as number of columns, influence of deformation in single column and stone column group, young modulus of the materials of stone column and soil, Poisson's ratio of column's material and soil have been studied. Results indicate that efficiency of stone columns in soft fine-grained soil. Most important results show that operations of stone columns are faster and less costly comparing to piles.

“…The bearing capacity of the treated ground is three to four times greater than that of the untreated ground (Bergado et al 1984;Bergado and Lam 1987). The following references were identified through this study, which can be of benefit in analyzing the bearing capacity of stone columns: , , Brauns (1978), Barksdale and Bachus (1983a), Guo and Qian (1991), Bouassida et al (1995), Van Impe et al (1997b), Jellali et al (2005), , Etezad et al (2006), Zhang et al (2009), , and Chambosse and Dobson (undated-b). Barksdale andBachus (1983a, 1983b) provide three analysis methods for slope stabilization: the Profile method, the Composite Shear Strength method, and the Lumped Moment method.…”
