ABSTRACT This case study describes the design and construction of an MSE (Mechanically Stabilised Earth) wall in the geological environment of the Taupō Pumice Formation, a non-welded ignimbrite and reworked deposits from the 181 AD Taupō eruption. The engineering properties of the pumice and the…
ABSTRACT During recent construction of an overpass bridge on soft ground, piled ground improvements were used to reduce the settlement of the bridge abutments and approach embankments. The piles were installed prior to construction of the approach embankments, under which significant consolidation settlement would occur…
ABSTRACT Inner city developments generally include deep basements that require perimeter retention to facilitate the excavation. Ground anchors are readily selected as part of the retention system due to their ability to be stressed and prevent structural movement. Ground anchors comprise steel components and often…
ABSTRACT The use of steel tendons in soil nailing and ground anchoring has been commonplace for both permanent and temporary applications. Double corrosion protection (DCP) is required to ensure a serviceable design life, and these have evolved to become complicated assemblies comprising numerous components. This…
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 On 23rd January 2019 a section of the Clifton beach coastline in Hastings collapsed. Approximately 25,000 m3 of rock fell from between 60 m to 110 m above beach level. Two tourists walking the popular route to the Cape Kidnappers Gannet Colony were…
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…
