Key words: Cyclone Gabrielle, KiwiRail, geotechnical, civil 1. Introduction As with a large portion of the North Island’s transport infrastructure, KiwiRail’s network was heavily impacted by Cyclone Gabrielle that occurred in February 2023. The Palmerston North to Gisborne Line (PNGL) was the most severely affected,…
Project: Slope Stability Guidance Documentation NZGS Leader Richard Justice Update The New Zealand Geotechnical Society have funding agreements with Toka Tú Ake EQC and MBIE for the development of Unit 1 of the proposed slope stability guidance series. This will be an overview unit, with…
23 MAY 2023 Government project delivers more reliable and resilient water source to Northland HON KIRITAPU ALLAN The Government has delivered the first of three significant water security projects in Northland, boosting regional business and climate resilience, with the opening of Matawii reservoir today, Regional…
Keywords Drone, landslide, cyclone, global, imagery Abstract The interpretation of aerial photographs has long been a valuable tool in terrain evaluation and identification of geomorphological features at a site. Publicly available aerial images for some parts of New Zealand date back to 1936 (such as…
Slope Assessed Risk Level Course(s) The first two courses were run in February in the middle of cyclone Gabrielle which provided additional realism and ‘in the field’ authenticity! It was certainly challenging ensuring the safety of the participants and providing access to suitable sites (as…
Abstract The recent update to the National Seismic Hazard Model has changed the approach to seismic site classification in New Zealand, with the time-averaged shear wave velocity over the top 30 m of the subsurface profile (VS30) at a site now being a key site…
We looked through the archives and found two landslip/land damage insurance related articles to jog the memory of the experienced and provide a history lesson for the not so experienced. The articles are topical with land damage from the recent major flood events, and replacement…
Keywords Liquefaction, risk assessment, planning, regional New Zealand 1. Introduction Since the Canterbury Earthquake Sequences (CES), liquefaction and its effects have been a focus for engineers and councils. There has been a significant amount learnt from these events in New Zealand due to the disproportionate…
Key words – light-weight fill, gravel raft, settlements, numerical modelling Abstract The use of Mainmark’s Terefil as an alternative to reinforced gravel raft for liquefaction mitigation and to minimise total static settlements and foundation differential performance under the building loads over soft cohesive and loose…
Our research programmes are advancing the science and implementation pathways of earthquake resilience through system-level science with highly integrated collaborations coordinated across the physical, engineering and social sciences and across multiple research institutions. The research is principally organised into Disciplinary Themes, Inter-disciplinary Programmes and Coordination…
