A stone column is used as a reinforcement technique for foundation design. The role of a stone column is to improve the load-bearing capacity of soft or weak soil by transferring the load from the foundation to the column. The column is made of crushed stones or gravel that are compacted in layers to form a vertical column. This increases the density of the soil and improves its strength, thereby reducing the settlement of the foundation. The stone column also provides vertical support, preventing the foundation from sinking or tilting. In addition, the column helps to improve the stability of the foundation and protects it against lateral motions, such as earthquakes or wind loads. Overall, the stone column is a reliable and cost-effective solution for improving the stability and load-bearing capacity of weak soil.
