Abstract The NZ Transport Agency Baypark to Bayfair link upgrade project will provide improvements to two key intersections on State Highway 2 in the east of urban Tauranga in the Bay of Plenty. The project will be constructed in an area which is susceptible to…
Abstract Loess and loess-derived soils cover much of Canterbury, from the foothills of the Southern Alps to the Pacific Coast. These soils are of variable thickness, ranging from several metres up to 40m at the base of slopes on Banks Peninsula. In many areas primary,…
Abstract The geological profile of a site and hence the determination of a site subsoil class can have a significant influence on the selection of a design peak ground acceleration (PGA) as derived from NZS 1170.5 (2004). At the New Plymouth Central Business District (CBD),…
Abstract Retaining wall design does not typically differentiate between levels of importance, particularly for static design. Walls that are more important, for example supporting importance level four buildings, are often designed to the same safety margins as relatively unimportant walls. Indeed, it can be argued…
Abstract The maximum shear modulus and liquefaction resistance of soils are fundamental input parameters in the non-linear dynamic analyses of soil structures. This paper focuses on the dynamic behaviour of natural pumiceous soils, which originated from a series of volcanic eruptions centred in the Taupo…
