A STUDY ON EFFECTS OF GEOSYNTHETIC ENCASEMENT ON FLOATING STONE COLUMN

There is tremendous effort required to treat the soft soil for laying foundation over it. In recent era researchers found little success to treat such a heterogeneous soft soil. The Geosynthetically encased stone column for improving such soft soil is now proven to be most effective one. Many researchers worked and proven the effectiveness of this method. Plenty of researchers worked on soft soil improvement using Geosynthetically encased stone column. Most of the research work done on unit cell idealization basis and the stone column rested over rigid bottom base of unit cell. However it is not necessary to have firm layer always available during actual field condition. So the present research work is all about treating the soft soil with Geosynthetically reinforced floating stone column. The bottom of the stone columns is rested over soft soil itself. Four types of Geosynthetic materials are used as an encasement. The load settlement responses were measured to know the effects of types of reinforcement on load settlement behaviour of floating stone column
