A MATERIAL CHARACTERISATION STUDY OF LATERITISED PALLID ZONE SOILS NEAR WORSLEY, WESTERN AUSTRALIA. PROCEEDINGS OF THE ELEVENTH INTERNATIONAL CONFERENCE ON SOIL MECHANICS AND FOUNDATION ENGINEERING, SAN FRANCISCO, 12-16 AUGUST 1985

The constitutive properties of the lateritic soils, near Worsley, located some 200 km south of Perth, W A, are the products of weathering and lateritisation of igneous rocks. These processes have produced a highly leached and cemented soil profile. Laboratory based testing will significantly underestimate strengths and over estimate the compressibilities of these lateritised soils. The camkometer (self boring pressuremeter) is most appropriate for testing these soils. The shear stress vs strain relationships thus derived show initial linearity to the peak stress followed by either work softening or hardening behaviour. Simplified models integrating geological causes with geotechnical effects are presented to explain their unusual constitutive properties. For the covering abstract of the conference see IRRD 287689.
