| Abstract | Stone columns are being widely used as ground reinforcing elements for the construction of flexible structures on soft soils. When they are installed in extreme soft soils, the possible squeezing of the stones in to the surrounding soil and intrusion of the clay in to the stone aggregate will result in poor performance of the stone column. In such situations confining the individual stone columns within a geosynthetic encasement would help in preserving the functions of the stone column as well as improving its strength and stiffness by many folds. In this paper the performance of the encased stone column has been evaluated through experimental studies and numerical simulations. The results have brought out the benefits of encasing the stone columns with geosynthetic, particularly in terms of enhanced load capacity. The influence of the geometry of the stone column, material properties like stiffness of the geosynthetic used for the encasement has been investigated. The numerical simulations generally agreed reasonably well with the experimental results. |
