Piled raft foundations are emerging out as a system for tall structures, especially in loose stratum. foundation, raft functions to provide a reasonable measure of stiffness and load resistance and the piles are provided to reduce the vertical settlements as well as the differential settlements in raft. effect of uneven lengths of piles and non performance of piled raft. Also, the effect of geometry of piles was studied by varying pile diameter, length, spacing and number of piles. The performance of analyzed in terms of Bearing Capacity Ratio (B.C.R.) and Settlement Reduction Ratio (S.R.R.). The research was carried out using finite element software MIDAS GTS 3D. It was concluded that use of uneven lengths of piles contribute in achievi in the construction of piled raft subjected to both uniform and non Increase in number of piles increased the bearing capacity, whereas, pile spacing, pile diameter showed no significant effect. The optimum length to diameter ratio (L/D) was found to be 20.
