ABSTRACT Landslides are widespread natural hazards that are responsible for substantial economic and societal damage globally each year. In New Zealand, landslides frequently occur on soil and rock, triggered by high rainfall, seismic activity, and land-use change and/or disturbance. This study focuses on the…
Abstract The Otway Ranges in southwest Victoria rank among the most susceptible areas for landslides in Australia. In December 2015, a bushfire led to significant loss of vegetation and property damage in the townships of Wye River and Separation Creek which are located on the…
ABSTRACT At the heart of a resilient community is building on land with a low instability risk. With population growth driving development in Northland new buildings are intersecting the area’s complex and commonly unstable geology on a frequent basis. For Northland to be building a…
. ABSTRACT The Jeffreys water supply pump station comprises replacement of the earthquake-damaged 200m3 concrete suction tank with a new 500m3 tank. Ground conditions at the site predominately comprise interbedded alluvial silt and sand in the surficial 8.75m, underlain by dense sandy gravel. Surficial soils…
ABSTRACT The existing literature contains no shortage of attempts at defining ‘collapsible soils’, all largely focussed on outlining the often unique properties and conditions required for collapse settlement to take place. First recognised and studied by Jennings and Knight (1957), collapse settlement can, in…
ABSTRACT With the significant growth currently being experienced in the foundations market it has been recognized by many of the leading geotechnical contractors that collectively they lacked a voice and ability to shape the industry in terms of quality, Health and Safety and general best…
ABSTRACT Resilience of our built environment is important for our societies faced with a range of natural hazards, anthropogenic hazards and climate change. This requires a fundamental rethink of our traditional established and codified design approaches. A focus on resilience is required from early…
ABSTRACT System response using dynamic effective stress modelling can capture the holistic behaviour of a potentially liquefiable soil deposit, including interaction between different soil layers. Compared to a conventional liquefaction triggering analysis, a system response assessment can either predict more or less damage depending…
ABSTRACT In September 2013 what was described as one of the most extreme rainfall events in New Zealand, hit the West Coast of the South Island. The storm claimed the lives of two Canadian tourists, closed State Highway 6 for two weeks and disrupted…
ABSTRACT Significant portions of land east of Great South Road in Takanini have been progressively rezoned for development since approximately 2004. With the introduction of the Auckland Unitary Plan, additional land has been identified for future urban development. This land is typically underlain by…
