The influence of tunnelling on piled foundations
View through CrossRef
A study of the influence of tunnelling on piled foundations was recently completed at the University of Cambridge. The study focussed on tunnelling near driven piles in dense sand and was carried out by means of centrifuge modelling. This paper presents a summary of the main findings, describing the mechanism controlling tunnelling-induced pile behaviour, a zone of influence around the tunnel where piles might be affected and recommendations for tunnelling near piles in practice. Both single piles and pile groups are considered.
