An Experimental Study on Vertically Loaded Driven and Bored Piles

Deep foundation is a kind of foundation used when the soil near to the top surface is incapable of resisting the super structure load. Pile foundation is one type of deep foundation, where the piles are used to transfer the load coming from the super structure to the deeper depth safely. Piles are subjected to different types of loading viz… vertical load, horizontal load etc., and the capacity of the piles to carry load also depends on various factors like diameter of pile, depth or length of pile, material of the pile used etc. Present work consists of group of piles of four numbers placed in circular, square, triangular shape. The piles used in study are of same cross sectional area, spaced at 2.5d (diameter of pile), 3d, and 3.5d centre to centre. The group of piles embedded in soil of different density (dense, loose, loose over dense and dense over loose) are tested for vertical loading.
