    Prediction of ground movements requires a reliable estimation of soil representative stress-strain behaviour. To do this an assessment of in-situ (‘preshear’) conditions and the associated influence on the average mobilised soil strength and strain is needed. While many studies focus on undrained shear strength, less effort has been reported for soil shear strain in the context of foundation design. The influence of different experimental and prediction techniques to determine representative soil shear stress-strain design parameters is worthy of study. In this paper, new experimental data is presented of from a series of triaxial and oedometer tests on kaolin. The results demonstrate increasing values of normalised undrained shear strength and reference shear strain with increasing OCR.
