ABSTRACT Design in New Zealand is increasingly requiring parameters obtained from in-situ seismic testing for use in modelling and assessment of the built environment. In New Zealand shear wave velocity (VS) profiles are most commonly required. However, the quality of in-situ seismic testing can…
ABSTRACT This study reports the results of an experimental investigation into the use of ground rubber (GR) products, at varying contents and sizes/gradations, as a sustainable solution towards improving the inferior geotechnical attributes of a subgrade clay deposit located in Adelaide, South Australia. A…
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 Following the M7.8 Kaikoura Earthquake GeoStabilization NZ Ltd (formerly Hiway GeoStabilization Ltd) were awarded the North Face Ohau Point Scaling and High Tensile Mesh Installation contract. The original design to mitigate rockfall hazards included a pinned high tensile steel wire mesh. The ground…
ABSTRACT This paper presents the results from direct shear testing of gravel-rubber mixtures through laboratory experiments and numerical simulations using discrete element method (DEM). Mixtures with volumetric proportions of 0%, 10%, 25%, 40% and 100% granulated rubber were tested using a conventional, medium-sized direct…
ABSTRACT Construction of a $77.8 million new hospital facility in Greymouth is nearing its completion. The geotechnical design framework used to mitigate liquefaction and lateral spreading is described. Design of the structural foundation systems required detailed consideration of subsidence, downdrag and lateral spread effects….
ABSTRACT Following the Canterbury Earthquake Sequence (CES) between 2010 and 2011, a number of the fire stations in the Canterbury area were severely damaged. The key aspect for the fire stations rebuild design was the philosophy of rebuilding with resilience, where the geotechnical design…
Jacobs Ladder – A Case-History of Debris Flow in a Post-Seismic Environment T.R. Justice NCTIR/ENGEO, Christchurch. ABSTRACT An increase in debris flows, and other slope stability events, over the short to medium term following significant seismic events is well recorded in international literature. The 2018…
