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…
In the June 2020 issue of NZ Geomechanics News ‘The Shrink Swell Test: A Critical Analysis’, Rogers et al., 2020, was published. This article provided an overview around the use of the Shrink Swell Test and current design practice for foundation design in NZ’s expansive…
ABSTRACT: Palmerston North City Council (PNCC) have identified a number of earthquake-prone buildings requiring seismic strengthening located along the ‘Priority Route’ in the City Centre. Seismic assessment (i.e. estimation of %NBS) and the subsequent design of strengthening schemes is heavily influenced by the Seismic Site…
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),…
SUMMARY Queenstown, New Zealand, is a known seismically-active area. A major soil type overlying the flat lands in and around the city is the varved micaceous clayey silt / sandy silt laminated lake sediment overlying the schist bedrock. In-situ (boreholes, CPTu, sCPTu, DMT, Vs and…
