Driven piles provide excellent stability to a structure by resisting lateral and vertical loads, such as those from wind and earthquakes. The impact force generated by the hammer causes the soil to compress around the pile, providing additional support and stability. In the current investigation, the overall behaviour of driven piles in multi-layered soil is assessed through finite element simulation. The soil domain comprises clay of soft consistency, loose sand, clay of medium consistency and dense sand at the bottom. The stroke applied on the top of the pile is simulated with the help of a harmonic loading system. In the study, the influence of parameters namely, pile diameter, water table depth, amplitude multiplier and soil constitutive models are examined on the behaviour of the driven pile. The results are presented in terms of settlement of the pile, excess pore water pressure phenomenon and shear stress development along the pile length. It is noticed that with the existence of a water table at the ground level, a high value of excess pore water pressure is generated at the bottom of the pile which enhances the settlement of the pile.
