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…
The project The New Dunedin Hospital (NDH) comprises two main buildings, the 11 storey Inpatient Building and the smaller five storey Outpatient Building, located on two adjacent city blocks on a new site near the existing hospital. With a price tag greater than $ 1…
ABSTRACT The Standard Penetration Test (SPT) is used worldwide and is perhaps the most common in situ soil test. A recent paper published in the June 2022 edition of Geomechanics News highlighted the use of the test in current New Zealand practice. This paper explores…
1. Introduction Further to the paper presented in NZ Geomechnaics News, Issue 98 in 2019 (Brook et al., 2019), there has been further progress in our research into naturally-occurring zeolitic mineral fibres such as erionite in New Zealand. This article is in response to several…
Background In 2016 I retired after fifty years involvement in civil and geotechnical engineering, having witnessed major changes in the techniques available to us and our knowledge of engineering geology and geotechnical phenomena. During that period, I was involved in some very interesting projects that…
This Specification sets out requirements for the construction of bored or driven pile types. This document is published in collaboration by the Structural Engineering Society New Zealand (SESOC) and the New Zealand Geotechnical Society (NZGS). This document supersedes the Auckland Structural Group publication “Piling Specification”…
Abstract The Christchurch Northern Corridor is a scheme involving the construction of a new 4-lane highway connecting the City of Christchurch to the Northern Arterial Motorway. The scheme’s site is predominantly underlain by up to 15m of alluvial deposits including very weak, highly compressible peat…
Abstract In the paper on cantilever pole walls presented in the June 2021 issue of NZ Geomechanics News (NZGN) a summary was presented of analysis methods for determining the lateral load capacity of the embedded pole foundations (Wood, 2021). The testing of rigid timber poles…
Abstract An issue faced by young geotechnical professionals is when to terminate the Standard Penetration Tests (SPT) when advancing a borehole during a geotechnical investigation. This issue commonly arises in the soil-rock interface zone where the ground mass is transitioning from a soil to a…
Abstract A multifaceted desktop and field based geotechnical survey and geohazard mapping project was completed for over 25,000 ha of mixed rural and urban land identified for potential future urban growth and development within the Kaipara District in Northland, New Zealand. The project included desktop…
