This article highlights the load transfer mechanism of disconnected piled raft (DPR) system based on scaled model experimental outcomes. The disconnected piles with less axial load are found to possess negative skin friction in the shallow depth making the load transfer process different from that of a CPR system.

Because of structural disconnection and low axial stress on piles, the DPR foundation has also the potential to immerge as a sustainable solution on account of low cement and steel requirement leading to less CO2 production.

摘要

This article highlights the load transfer mechanism of disconnected piled raft (DPR) system based on scaled model experimental outcomes. The disconnected piles with less axial load are found to possess negative skin friction in the shallow depth making the load transfer process different from that of a CPR system. More over the settlement efficiency of DPR is observed to have a keen dependency on the cushion material and cushion thickness. Because of structural disconnection and low axial stress on piles, the DPR foundation has also the potential to immerge as a sustainable solution on account of low cement and steel requirement leading to less CO2 production.
