DESCRIPTION:All structures in contact with the ground require foundations 
 to resist loads. For small-scale projects shallow foundations are often th
 e most economical. In general\, the design of a shallow foundation is gove
 rned by the settlement\, rather than the ultimate bearing capacity. Settle
 ments are predicted based on elastic properties of soil. Soil is\, however
 \, non-linear even at small strains. A series of centrifuge experiments\, 
 each with three shallow footings\, were performed on clay and saturated sa
 nd models at the Schofield Centre. Photographs taken at short intervals al
 lowed the technique of Particle Image Velocimetry (PIV) to be utilised. Ot
 her instrumentation was also used to confirm various quantities. The testi
 ng method\, techniques adopted and results from the centrifuge experiments
  are given and discussed. Some analysis of the results has been performed 
 with one theoretical mechanism\, developed from centrifuge results\, given
 .
