Installation of Pile Group in Overconsolidated Clay

Measurements made during and immediately after the installation of a full-sized group of nine driven piles and two isolated control piles are presented. Rates of pile set-up in saturated, desiccated overconsolidated clay, development of lateral pressures on the piles, ground movements and accumulation of residual loads in the piles are described. Note is made of the similarities between group and isolate isolated piles.
