Abstract Routine effective stress analyses for failure of geotechnical structures use a linear Mohr-Coulomb envelope and routine analyses for ground movements use linear elasticity with constant Young’s Modulus E’ or one-dimensional modulus M’. Observations of soil behaviour show that strength and stiffness are non-linear and…

Presented by Professor John Atkinson Senior Principal, Coffey Geotechnics Emeritus Professor of Soil Mechanics, City University London on 28 November 2017 at Auckland University. The talk describes how to investigate and model the ground, how to determine parameters and how to perform simple analyses. A…
Ground engineers routinely use simple relationships – rules of thumb – to obtain soil parameters and to design ground works. Some of these have a sound theoretical basis and can be applied generally while some are purely empirical and so should be applied only within…
