ABSTRACT
A large number of electrical cone penetration tests have been carried out within a 50 m by 50 m area of the Adelaide city in order to investigate the small-scale variation of the shear strength of a stiff, overconsolidated clay. The tests, 201 in all, and at a grid spacing of either one and five metres, were taken to a typical depth of 5 metres. Measurements of cone tip resistance and sleeve friction were recorded at intervals of 5 mm. This paper examines the results of a subset of these tests, that is, those carried out in a 25 m by 25 m area, and applies the technique of geostatistics, in order to develop a model for the spatial variation of the shear strength of the clay.
