· Stone columns (SCs) and sand compaction piles (SCPs) are widely utilized as effective methods to increase the bearing capacity and reduce the settlement of soft ground. In this study, a physical model test was conducted to compare the performances of the SC- and SCP-improved Hong Kong Marine Clay (HKMC) grounds.

· The stone column is designed as per IS 15284-2003 and is usually analyzed by using the unit cell concept. They are generally constructed using crushed stone aggregates and are ideally installed in an equilateral triangle pattern. The failure of the stone column is dependent on its critical length.
