This article was previously published in NZ Construction in June/July 2019 and is reproduced by permission. It would be an understatement to say that the Christchurch earthquake created a series of major headaches for those tasked with the monumental challenge of rebuilding the city. But it…
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…
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…
Abstract A proposed expansion at the Lyttelton Port of Christchurch in New Zealand consists of the reclamation of approximately 34 hectares of new land and the construction of a new wharf supported on piles. Seismic response of the reclamation and soil-pile interaction have been key…
Abstract A site-specific geotechnical engineering approach was proposed as part of a seismic retrofit design of a multi-storey building in Christchurch CBD (Central Business District). Various analytical techniques were utilized including Probabilistic Seismic Hazard Analysis (PSHA), development of time histories, Site Specific Response Analysis (SSRA),…
Abstract Following the companion study of McGann et al. [1], seismic piezocone (SCPTu) data compiled from sites in Christchurch, New Zealand area are used with multiple linear regression to develop a Christchurch-specific empirical correlation for use in predicting soil shear wave velocities, Vs, from cone…
Introduction Ground remediation methods have been used for many years to improve ground conditions to enable development. Ground remediation has become increasingly common as industrialisation has caused rapid development of cities. Areas within cities, previously undeveloped due to adverse ground conditions, can now be remediated…
Abstract In fulfilling its vision and purpose Lyttelton Port of Christchurch (LPC) intends to create new land in Te Awaparahi Bay through a land development programme. The programme involves reclamation of approximately 34ha of new land and the construction of a new 700m wharf, to…
Lateral spreading occurred proximal to waterways during the 2010 to 2011 Canterbury Earthquake Sequence (CES) resulting in severe damage to overlying infrastructure. Published empirical and semi-empirical models for predicting lateral spread displacements have been shown produce displacement that varied by a factor of <0.5 to…
During the Christchurch Earthquakes in 2011, the cliffs at Clifton Hill and Moa Bone Point experienced significant ground shaking and as a result a large amount of material was lost from cliff collapse and mass movement. The sites at Clifton Hill and Moa Bone Point…
