Parametric Study on the Interaction Factor of Piled Raft
MetadataShow full item record
The performance of the piled raft foundation system depends upon the interaction level between the raft-soil-and the pile group. Understanding of this process is more complicates than the conventional pile group as the raft in contact with the ground influences the confining pressure, making the interaction behaviour more complicated. This paper presents a qualitative and a quantitative assessment of the interaction behaviour through a non dimensional interaction factor, through the results of a series of 1 g model studies. The effect of various important parameters like pile length, pile raft area ratio and spacing on the interaction factor are discussed.
