Below are a series of questions put to Laurie Wesley by Rafael Iglesies, with Laurie’s responses. The Editors thank Laurie for sharing these thoughts and insights, they make interesting reading! 1. In many parts of Chile we can easily find high-rise residual soil slopes right…
In this paper, the properties of undisturbed Auckland residual soil are related to visualisation of the void structure obtained by X-ray CT scanning. The soil investigated was derived from in situ weathering of the Waitemata group sandstones and siltstones, a process which produces soil with surprisingly…
The manner in which the results of oedometer tests are normally presented and used for determining stiffness parameters is examined. The basis for using a logarithmic scale for pressure is examined and shown to be of limited relevance to many soils. It is suggested that…
This paper presents an application of a bubble model (a non-linear multi-surface kinematic hardening soil model), implemented in the FLAC software, to simulate the stress-strain behaviour measured in an undrained triaxial compression of Auckland residual clay. The workings of the model are explained in a qualitative…
The purpose of this paper is to present results of field testing to evaluate the lateral capacity of timber poles embedded in Auckland residual clay. The work was undertaken because the commonly used relation by Broms seems to predict lateral capacities for embedded poles used in construction of…
A total of 29 CPT soundings up to depths approaching 10 m were made at close spacings, so that an intensive exploration was made of the properties of a limited volume of residual soil in the Albany area of Auckland. Since the soil was derived from in…
