Prediction of settlements of both large and small spread footings on sand has traditionally been carried out using methods which are largely empirical. In recent years, advances have been made both in the understanding of the importance of non-linearity in the stress-strain response of soil, and in methods of measuring this response. It is therefore timely to re-examine the methods of predicting settlements in soils - particularly sands - and to begin the process of developing more rational approaches to settlement prediction. This paper outlines a framework within which such methods might be developed. A technique is described for measuring the stress-strain response of sand in situ, using the seismic cone and self-boring pressuremeter, and data are presented from a sand site in Perth, Western Australia, Australia.
