MoreEvaluation of Piled Raft Foundations Behavior with Different Dimensions of Piles. Journal of Applied Sciences, 10: 1320-1325. In a piled raft foundation, the total load of the superstructure is partly carried out by piles through skin friction and the remaining load is taken by raft through contact with the soil.
MoreApr 19, 2019 Current foundation design practice considers conventional pile group foundation when simpler and rather economical raft foundations do not meet one of the design criteria. However, design requirements could be met by incorporating a reduced number of piles with the raft. Piled Raft foundation (PRF) is a composite foundation in which, the piles and the raft contribute to the total
