Abstract
This study presents an experimental investigation on behavior of piled raft system in sandy
soil. A small scale “prototype” model was tested in a sand box with load applied to the
foundation through a compression jack and measured by means of a load cell. The load vs
settlement is observed for different configuration of piled raft system. The configurations of
pile groups are unpiled raft, raft with 1,2,3,4,6,9,12,16 piles were tested in the laboratory, in
addition to tests for varying raft thickness & pile length. The results of the tests show the
effectiveness of using piles as settlement reduction measure with the rafts. As the number of
settlement reducing piles increases, the load improvement ratio increases and the differential
settlement ratio decreases & as the length of the pile increases the settlement reduces.
