When soil of low bearing capacity extends to a considerable depth, piles are generally used to transmit vertical and lateral loads to the surrounding soil media. Pile foundation is used to transmit vertical and lateral loads to the surrounding soil media either as a single / mono pile or group piles. Behaviour of pile group under vertical and lateral loading is examined in clayey soil on steel pipe piles with external diameter and inside diameter of 25mm and 19mm respectively. 300 mm, 400 mm and 500 mm pile length is adopted for experiment work. For this study, pile cap made up of steel plate of size 200mm × 200mm × 20mm is used. The circular R.C.C. model tank with external diameter and inside diameter of 1000mm and 900mm respectively and height of 900mm is used. The dimension of base plate is taken as 1100mm × 1100mm and thickness of plate is 10mm. The effect of slenderness ratio (L/D) of 12, 16, and 20 on a small scale pile group configuration (2×2) is also examined by varying the pile length. The combined vertical and lateral loads were applied in two stages. In the first stage, vertical load was applied and then in the second stage, lateral loads were applied incrementally while keeping the vertical load constant. Results indicate that the load - displacement behaviour is nonlinear. Hollow pile foundation examination will be the most productive pile foundation technique as far as economy, stability, construction methods and post settlement problems to transfer to heavy loads safely to greater depths.
