ABSTRACT The Mw6.2 22 February 2011 and Mw6.0 13 June 2011 earthquakes caused significant and wide-spread damage to the Christchurch infrastructure networks, including the Christchurch water networks (potable, waste, and storm). The transient and permanent ground deformations generated by these two earthquakes severely damaged buried…
ABSTRACT The Magnitude (Mw) 7.8 Kaikōura earthquake struck the east coast of the South Island of New Zealand in November 2016, resulting in widespread damage to the slopes along the Kaikōura coast. Many of the subsequent remediation measures relied on rock anchors, and a significant…
ABSTRACT Waka Kotahi, the New Zealand Transport Agency (NZTA), under its policy of providing a safer and more resilient road network, has adopted the NSW Government Transport, Roads & Maritime Services ‘Guide to Slope Risk Analysis’ to provide a consistent methodology for assessing safety to…
ABSTRACT Considered as the strongest storm to hit Japan in more than six decades, the super-typhoon “Hagibis” (locally referred to as Typhoon No. 19) struck the central and eastern parts of the country on 12 October 2019 and caused widespread damage across many low-lying…
ABSTRACT The design and construction of temporary working platforms for cranes and piling rigs is a high-risk activity and requires the careful selection of the appropriate input parameters to obtain the correct load cases as well as the application of robust and reliable design methods…
ABSTRACT The lateral load transfer between a pile and laterally spreading ground during an earthquake is a complex soil-structure interaction problem given the significant nonlinear behaviour of soils during such an event. This interaction becomes more complex when piles are used as a retaining…
ABSTRACT This paper presents proposed shear wave velocity-depth relationships for six prominent geological formations from the Nelson-Tasman area. Shear wave velocity profiles were developed for a selection of sites across the Nelson-Tasman Region using a combination of active source and passive source surface wave testing…
ABSTRACT The State Highway network in Eastern Bay of Plenty crosses terrain with varied geomorphology and geology with a range of landslide types presenting a major geological hazard. This paper presents examples of recent landslides that have affected the highway network, including the underlying geological…
ABSTRACT Tauranga is one of New Zealand’s fastest growing cities and port economies. The city is susceptible to many natural hazards therefore resilience planning is imperative to its future. As part of Tauranga City Council’s Resilience Programme, a city-wide liquefaction study has been completed, comprising…
ABSTRACT On 26th November 2017 a localised thunderstorm cell over the hills behind Roxburgh, Central Otago, produced up to an estimated 150mm of rain over a three-hour period. Four catchments experienced severe flooding and sediment movement (debris flows or debris floods), resulting in significant sediment…
