As they flew along the newly formed Greendale Fault in September 2010, there were many things that Dr Simon Cox and his GNS Science colleagues could see were clearly awry during the first aerial reconnaissance. But among the offset roads, bent hedgerows and fences, torn…
The Earthquake Geotechnical Engineering Practice Series (the Modules), published jointly by MBIE and NZGS during 2016 and 2017, is currently being updated. Feedback from users is now being incorporated and new research and information is being incorporated to continue to assist design professionals to improve…
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 Unmanned Aerial Vehicles (UAVs or drones) facilitate data collection that allows rapid and enhanced geotechnical assessment of the risks associated with landslides, slopes and structures, during…
Prepared by sally Dellow and Chris Massey on behalf of the GeoNet Landslide Team and the USGS and GEER reconnaissance teams 1 The November 14, 2016, Mw 7.8 Kaikoura earthquake triggered thousands of landslides over a total area of about 10,000 km2, with the majority…
NCTIR Geotechnical Team The North Canterbury Transport Infrastructure Recovery (NCTIR) has been set-up by the government under the Hurunui/Kaikoura Earthquakes Recovery Act 2016. Its purpose is to repair and re-open the earthquake-damaged road and rail networks between Christchurch and Picton by the end of 2017….
Lecture Summary There is a growing emphasis on Displacement Based Earthquake Design (DBD) analysis for buildings, retaining walls and bridge structures. DBD is specified as the preferred design method for highway structures in a draft revision of Section 5 of the Bridge Manual (NZ Transport…
Introduction The M7.8 Kaikoura earthquake of 14 November 2016 generated very large peak ground accelerations (PGA’s) that resulted in the closure of the coastal sections of both State Highway 1 and the Main North Railway Line due to slope failures originating from above the road…
Abstract Currently, there is an increasing interest in providing more sustainable solutions for mitigating liquefaction and interdisciplinary work has started to introduce the use of nano-materials for this purpose. These materials have some advantages when compared with traditional techniques. For instance, they could be injected…
This document has been produced in response to the Canterbury earthquake sequence that started on 4 September 2010 with the Darfield earthquake. The intention of this document is to provide guidance on what should be included in a technical specification when designing and constructing ground improvement (for liquefaction mitigation purposes)…
