Abstract: Stone columns repeatedly used for stabilization of soft soils. For the support of different structures, use of stone columns is increasing day by day. Stone columns are used for the improvement of settlement and bearing capacity of soft soils in reasonable fare and friendly towards the environment. In present paper, a review to analyse the behavior of stone columns used in different types of constructions such as oil storage tanks, embankments, buildings etc. The consequence of without encased and encased stone columns on several types of construction is studied. The effect of various diameters with various depths in ground also reviewed. For the encasement different types of geosynthetics are used for improvement of the results. For the prediction of the settlement of foundations reinforced with stone column number of numerical and physical approaches are done. This paper deals with several theories exist from past to present which helps in understanding the enhancements by stone columns in boosting soft soils. In development of geotechnical properties physical modelling has an important role.
