The paper presents the results of centrifuge tests performed on piled raft foundation models. The model raft consisted of a circular very stiff plate; the model piles, embedded in loose saturated very fine sand, were non-displacement; some of them were instrumented with two load cells, the first at the pile head, the second at the tip or, alternatively, at mid-pile, to determine the distribution of load along the shaft. The fol-lowing models were tested: the rigid plate without piles, an isolated pile and the piled raft with 1, 3, 7 and 13 piles respectively. The results of the tests carried out have been analysed with the aim of investigating the raft-soil-pile interaction mechanisms and understanding how the load bearing behaviour of the piles as part of a piled raft changes compared to an isolated pile. The paper describes the details of experiments undertaken and some of the results.

Abstract

The paper presents the results of centrifuge tests performed on piled raft foundation models. The model raft consisted of a circular very stiff plate; the model piles, embedded in loose saturated very fine sand, were non-displacement; some of them were instrumented with two load cells, the first at the pile head, the second at the tip or, alternatively, at mid-pile, to determine the distribution of load along the shaft. The fol-lowing models were tested: the rigid plate without piles, an isolated pile and the piled raft with 1, 3, 7 and 13 piles respectively. The results of the tests carried out have been analysed with the aim of investigating the raft-soil-pile interaction mechanisms and understanding how the load bearing behaviour of the piles as part of a piled raft changes compared to an isolated pile. The paper describes the details of experiments undertaken and some of the results.
