STABILIZATION OF SOFT SOIL USING STONE COLUMN – THE REVIEW

Abstract

Ground improvement techniques based on stone column are broadly used in construction industries. It is the very effective method for improving the engineering properties of soil in all aspects and reduces the settlement problem in poor grounded soil such as silt, clay and silty sand. Stone columns are installed using either top or bottom feed system accompanied with or without jetted water. The stone column mainly consists of compacted aggregates like gravel or crushed stone which is aligned by the vibrator. The stone column are very effective in cohesive soil when compared to the sand and silty soil. The permeability rate in sand and aggregates are high and allow the pore pressure dissipates in short time. The commonly used methods for installing the stone columns are vibro replacement and vibro displacement. This review paper also projected for designing the effectiveness of stone column technique in problematic soil.
