Abstract: There is no doubt that the influence of column material is considered so important to be studied in the performance of the stone column through laboratory experiments on models stone columns which are installed in clayey soil. In current study two reinforcement materials were being studied; stone and sand. In addition, settlement versus load response was determined. The main controlling parameter in the design of the stone column is the grain size of the stone columns material. Under the same loading condition, the weak soil was also analysed and it has been found that the stones are the most effective material. Furthermore, experimental study on the behaviour of a group of four and eight columns was carried out through the finite element analysis with the Software PLAXIS 3D by using 16-noded triangular elements. It has been concluded that the inclusion of piles considerably improve the load-deformation properties of a clay soil. Through studying different pile materials which were used in this study, it has been found that the stones were more effective than sand for single column and group of columns.
