Parametric Study Using 3D Numerical Analysis on Stone Columns

A common and very efficient method for strengthening soft soils, supporting foundation stability, reducing differential settlement, increasing the bearing capacity of soft soils, and enhancing their overall performance is the use of stone columns, which has been widely welcomed by geotechnical engineers. Particularly when used with somewhat lightweight buildings, these columns demonstrate increased effectiveness. The finite element method (FEM)-based programme Plaxis 3D was used to run numerical simulations in this research work to examine the behaviour of stone columns. The goal of this study explores many factors, including columns diameter, length, and material characteristics which affect the performance of stone columns on the stability and geotechnical qualities of soft clayey soil. The upgraded ground's improved load-carrying capacity is carefully studied, both qualitatively and quantitatively. The results of the investigation show a notable increase in the stone columns’ ability to support loads, highlighting their load-carrying capacity and reduction in bulging of stone columns as a dependable ground improvement solution.
