Flagship Programme 2

Liquefaction Impacts on Land and Infrastructure
Leader: Misko Cubrinovski
Deputy Leader: Sjoerd van Ballegooy
Industry Representative: Sjoerd van Ballegooy
This flagship will develop new approaches and methodologies for quantification of impacts of soil liquefaction on land and infrastructure through a fundamental understanding of onset and consequences of liquefaction; and use 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 levels.
Key Thrust Areas
1: Liquefaction Evaluation: Beyond Current State-of-Art-and-Practice
Development and improvement of liquefaction assessment methods (Liquefaction Evaluation: Beyond Current State-of-Art and Practice). Utilize the exceptional databases compiled during Canterbury and Kaikoura Earthquakes, and obtain additional high-quality data where needed, to develop new or improve existing liquefaction evaluation procedures (field, laboratory and analytical tools and methodologies) that will adequately address current and future society needs for performance of land and infrastructure during earthquakes.
2: Liquefaction Vulnerability of New Zealand Land and Infrastructure
Identify critical issues and ground conditions related to liquefaction impacts on infrastructure, including characterization of important but challenging New Zealand soils, and the development of adequate assessment procedures and cost-effective mitigation strategies.
3: Liquefaction Assessment and Mitigation: Systems Approach
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 know-how within cross-disciplinary tools and methodologies.
