A Review on Different Approaches of Piled Raft Analysis

Ripunjoy Deka

A raft foundation that supported by piles is proved to be an economical foundation system, if the bearing capacity of the raft is adequate to withstand the loads from superstructure. Then the piles located strategically to support the raft can reduce the both overall and differential settlement of the foundation system. In this paper, different approaches for the analysis of piled raft foundations forwarded by different researchers from time to time are reviewed and their capabilities and limitations are also discussed. Some of the approaches are useful only for preliminary design, while others are useful for detailed design.
