Research Report 553 The development of design guidance for bridges in New Zealand for liquefaction and lateral spreading effects

Published: | Category: Road assets , Research & reports | Audience: General

This report presents a summary of the outcomes from a research project commissioned by the NZ Transport Agency to develop design guidance for bridges in New Zealand for liquefaction and lateral spreading effects. The study involved review of relevant case studies and available design methods. The report summarises available design procedures that are based on observed seismic behaviour of bridges and on the most recent research findings, and identifies design methods appropriate for New Zealand conditions. The report also considers issues associated with liquefaction and lateral spreading and their effect on bridge structures and summarises requirements for geotechnical investigations, evaluation techniques for liquefaction and lateral spreading, methods of ground improvements, methods of liquefaction analysis, structural mitigation solutions, construction and monitoring issues. The report also identifies areas where supporting information is not available and further research work is required.
