Turning issues into opportunities in the New Zealand context Abstract End-of-life tyres (ELTs) are non-reusable tyres in their original form. They enter a waste management system based on product/material recycling and energy recovery or go to disposal. In New Zealand, only 30% of the 5…
Originally Published on LinkedIn, 11 January 2015. Republished by permission of the author. The Generalised Hoek-Brown (GHB) criterion is likely to be, in one form or another, the most widely used rock mass strength criterion in geotechnical engineering practice, despite its semi-empirical nature or any…
The Earthquake Commission (EQC) has, for a long time, been an important investor in high quality research in New Zealand. EQC’s research programme spans science, engineering and social science and has played a vital role in supporting New Zealand’s improved resilience to natural hazards. Through…
Prepared for the 69th Highway Geology Symposium, September, 2018 ABSTRACT The November 2016 M7.8 Kaikoura earthquake resulted in excess of 40 landslides that directly impacted the key road and rail corridor on New Zealand’s South Island. Within two months, the New Zealand Government formed the…

This paper was originally published in Australian Geomechanics in September 2018 and is reproduced by permission of AGS ABSTRACT Three dimensional geological models are increasingly being used to characterise the world of ground engineering. Soil, rock, geological structures such as faults, rock fall zones and…
Abstract On 12 October 2019, super-typhoon Hagibis (locally referred to as Typhoon No. 19) made landfall in Japan and caused extensive damage to a wide area, especially in the Kantō Region. Considered as the strongest typhoon to hit the country in 60 years, the typhoon…
ABSTRACT Three important aspects in the engineering assessment of soil liquefaction, i.e. material characterization of liquefiable soils, in-situ state characterization of soils, and system response of liquefiable deposits are the subject of this paper. These aspects in the assessment are especially important in the evaluation…
