Abstract

The London Geotechnical Centrifuge Centre at City University London is a major experimental research facility for the Geotechnical Engineering Research Group. Some findings from two recent doctoral research projects are presented. The projects were aimed at improving our understanding of piled foundations. Pile group behaviour was studied with particular emphasis in determining the efficiency and load capacity of non standard group arrangements. The project was related directly to a development in London UK in which high capacity foundations were constructed using a Perimeter group arrangement of minipiles since that was all that could be constructed given onerous site constraints. The centrifuge research gave new insights into how pile groups carry large loads and demonstrated that Perimeter group arrangements make much more efficient use of piles than Grid groups. The second project was again industry driven and demonstrated that modifying the profile of a pile shaft can give significant increase in capacity with relatively little additional pile material.
