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…
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…
