strong>Flagship Summary
This flagship will develop new approaches and methodologies for quantifi=
cation of impacts of soil liquefaction on land and infrastructure through a=
fundamental understanding of onset and consequences of liquefaction; and u=
se these methods to assess liquefaction impacts throughout New Zealand and =
their potential to be mitigated. These novel methods will represent a=
major advance in the field, and will provide means for a robust assessment=
and treatment of liquefaction hazards at both site-specific and regional l=
evels. The key thrust areas are:
- Development and improvement of liquefaction assessment methods (Liquefa=
ction Evaluation: Beyond Current State-of-Art and Practice). Utilize the ex=
ceptional databases compiled during Canterbury and Kaikoura Earthquakes, an=
d obtain additional high-quality data where needed, to develop new or impro=
ve existing liquefaction evaluation procedures (field, laboratory and analy=
tical tools and methodologies) that will adequately address current and fut=
ure society needs for performance of land and infrastructure during earthqu=
akes.
- Identify critical issues and ground conditions related to liquefaction =
impacts on infrastructure, including characterization of important but chal=
lenging New Zealand soils, and the development of adequate assessment proce=
dures and cost-effective mitigation strategies.
- Development of performance based criteria for micro systems (e.g. soil =
deposits; soil-foundation-building systems) and macro systems (urban areas;=
land use and development) and lifeline networks, integrating geotechnical =
engineering knowhow within cross-disciplinary tools and methodologies.
