Abstract
Recent earthquakes in New Zealand and Haiti have shown the widespread damage suffered by pile foundations owing to soil liquefaction and lateral spreading. Several failure mechanisms of piles in liquefiable soils such as pile buckling and excessive settlement of piles in liquefied soil layers were developed at Cambridge University based on extensive centrifuge experiments. It will be shown that some of these anticipated failure mechanisms of pile foundations are confirmed by the observations in New Zealand and Haiti. The value of dynamic centrifuge modelling in deciphering the pile behaviour through observation of failure mechanisms is established. Further it is proposed that dynamic centrifuge modelling can be a valuable tool for forensic engineering in the area of geotechnical earthquake engineering.
