Abstract

As part of a series of experiments to investigate the effects of tunnelling on bored piles carried out at the Cambridge University Geotechnical Centrifuge, a new and novel model pile design is presented. The pile is semi-circular in cross section allowing the sub surface displacements around the pile toe to be monitored using particle image velocimetry (PIV). The new pile design, along with the loading mechanism, ensured the load was transmitted predominantly though the pile centroid, which reduced the bending effects which have previously caused significant errors in these types of problem. The pile load cells at the head and the base were also placed along the pile centroid to minimise the effects of bending on the load measurement. The paper presents the results of a centrifuge pile loading test, illustrating the excellent response of the load cells within their working range and the high quality PIV data which was obtained through this novel modelling approach.
