Abstract EN
Over the past few decades, interest has grown about the role of the piled raftstructure in soils.
A structural fill cushion separates the piles from the raft in theform of an unconnected piled raft base (UCPRF).
Given the advantage of thisstructure, the load is dispersed between the raft and the piles by the cushion.
Thecushion serves as a load redistributor between the raft and the piles.
Loaddispersion capability of the system was theoretically estimated using PLAXISfinite element analysis software in this study.
The effect of cushion thickness onsettlement reductions was investigated as well.
Obtained results showed that thepile head has the greatest axial stress in the piled raft system.
, however decreasedalong the length of the pile according to finite element analysis.
The unconnectedhead's maximum axial load is transferred down to a point a certain distance belowthe pile head (approximately two meters in the studied model).
Above the top twometers, the axial stress in the pile begins to decrease, following the same patternas the connected system.
The thickness of the cushion affects the load sharingbetween the cushion and the piles.
