ABSTRACT The accurate knowledge of the geological, geotechnical, geophysical and geometrical characteristics of soil conditions at urban area, usually obtained through microzonation studies, is generally important to the seismic hazard and risk assessment, and consequently for decision-making with respect to the reduction of earthquake-induced losses…
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…
ABSTRACT Standard penetration test (SPT), cone penetration test (CPT) and vane shear test (VST) are the most common in-situ tests around the world due to their high capabilities in soil characterisation and estimation of shear strength parameters of soil. Screw Driving Sounding (SDS) is…
Abstract The Ward to Cheviot section of State Highway 1 is a key lifeline transportation route that runs through the Kaikōura township. Its strategic importance on the national state highway connecting the North Island via the Wellington-Picton ferry to the city of Christchurch in the…
