     one of the best improvement technique on soft clays is the installation of geosynthatic encased stone columns. a numerical analysis was carried out using plaxis software and the effectiveness of geosynthetic in reducing the settlement of single foundation resting on a geosynthatic encased stone column was investigated through a parametric study. a drained analysis was carried out using mohr-coulomb’s criterion for soft clay and stone. the geogrid element was used to model the geosynthetic and was modeled as linear elastic element. based on the results of these analyses, warping the stone column with geosynthetic, significantly reduces the lateral bulging, which occurs at top sections of ordinary stone column during loading, and increases the transfer of axial force to lower depths too. the role of encasement in reducting the settlement is superior for higher surface pressure. the adequate depth for encasing is lesser than the length of the column. encasing beyond this depth does not effective in reducing settlement.
