Abstract

Piled foundations are used in the cases where the structural loads cannot be carried safely

with the shallow foundations. Piled raft foundation has become a prominent foundation

system in recent years due to that it combines load bearing capacities of piles and raft.

Therefore, comprehensive analytical and experimental studies have been carried out for

reliable and economic design of piled raft foundations. In this study, the effects of design

parameters of piled raft foundations in sand (pile spacing, pile diameter, pile length and

relative density etc.) have been investigated experimentally. In the laboratory tests, model

composite (steel and concrete) piles with diameters of 20, 30 mm and lengths of 200, 300

mm were used.The raft was made of steel plate with plan dimensions of 160x160, 240x240

mm and a thickness of 6 mm. The model piled raft foundations with different design

parameters were tested. From the tests results, as the pile spacing getting larger, the bearing

capacities of the model pile raft foundation increased up to a limit value and the optimum

distance between the piles was determined to be 4D. Some design parameters are suggested

for use in foundation engineering applications.
