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…

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…
