Simplified Design Procedure for Piled Raft Foundations
In situations where a raft foundation alone does not satisfy the design requirements, it may be possible to enhance the performance of the raft by the addition of piles. The use of a limited number of piles, strategically located, may improve both the ultimate load capacity and the settlement and differential settlement performance of the raft. This paper outlines the development of a simplified method of analysis which can provide a useful tool for preliminary design of piled raft foundations. It involves two phases: 1) The assessment of the overall foundation behavior and 2) The assessment of the behavior under individual column loads. In both cases, use is made of simplified solutions to compute foundation stiffness and capacity characteristics. The selection of design geotechnical parameters is an essential component of both design stages, and some approximations for estimating the necessary parameters are summarized. Typical applications to a case history of a piled raft and to model centrifuge tests are described, and it is found that the behavior predicted by the simplified analysis is broadly consistent with the measured behavior.
