ABSTRACT Significant portions of land east of Great South Road in Takanini have been progressively rezoned for development since approximately 2004. With the introduction of the Auckland Unitary Plan, additional land has been identified for future urban development. This land is typically underlain by…
ABSTRACT The Wynyard Edge Alliance (Auckland Council, the Crown represented by Ministry of Business, Innovation and Employment, Downer, McConnell Dowell, Beca, Tonkin & Taylor Ltd) was formed to design and construct the infrastructure to support the 36th America’s Cup event in Auckland. In addition…
ABSTRACT The City Rail Link project connects the existing Britomart rail terminus in Auckland’s CBD with the Mt Eden Station on the North Auckland Line. The c.3km-long route traverses a wide range of geology and ground conditions. Most of the tunnelling will be within…
Introduction The Auckland Unitary Plan (AUP) introduced new regulations for groundwater take and diversion in the Auckland Region. Whilst the authors of the rules unquestionably had the correct intentions, the interpretation and application of the regulations has been overly conservative and lacking in context. The…
Abstract This paper describes a study on seismic coefficient and dynamic earth pressure distribution of a geo-grid reinforced Mechanically Stabilized Earth (MSE) retaining wall. Dynamic finite element modeling is implemented on the wall to investigate its dynamic responses under selected historic ground motions for a…
Abstract The shrink swell test, which combines both the shrink strain and the swell strain, was developed in Australia in the 1980s. This test now underpins a codified approach to the foundation design of lightweight buildings on expansive (reactive) soils in Australia and New Zealand….
This paper was originally published in Australian Geomechanics in September 2018 and is reproduced by permission of AGS ABSTRACT Unmanned Aerial Vehicles (UAVs or drones) facilitate data collection that allows rapid and enhanced geotechnical assessment of the risks associated with landslides, slopes and structures, during…
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…
Figure 1: Auckland’s reclamation zones are north of the original 1840’s shoreline (red). Map shows historic bays (light blue), headlands (yellow), paleo-river/stream channels (white arrows showing direction of flow). The surface represents the depth to unweathered ECBF based on subsurface site investigation data and geomorphic…
