EXPERIMENTAL STUDY ON BEHAVIOUR OF STONE COLUMN ON SOFT SOIL WITH AND WITHOUT GEOSYNTHETICS

The fine grained soils such as soft clays, loose silts and most organic soils are characterized by low undrained shear strength, low bearing capacity, high compressibility and low permeability. These lead to soil stability problems when construction work is taken on such type of soil. On account of poor permeability of the soil, the dissipation of pore water is very slow. It takes a long time for the soil to consolidate and stabilize on its own, thereby delaying the construction activities on such soils. In such situations, soil needs stabilization before construction. Hence suitable ground improvement method has to be adopted to improve the engineering properties of soil
