- Summary
Soil liquefaction and resulting ground failure due to earthquakes presents a significant hazard to distributed infrastructure systems and structures around the world. Currently there is no consensus in liquefaction susceptibility or triggering models. The disagreements between models is a result of incomplete datasets and parameter spaces for model development. The Next Generation Liquefaction (NGL) Project was created to provide a database for advancing liquefaction research and to develop models for the prediction of liquefaction and its effects, derived in part from that database in a transparent and peer-reviewed manner, that provide end users with a consensus approach to assess liquefaction potential within a probabilistic framework. An online relational database was created for organizing and storing case histories and laboratory data which is available at http://nextgenerationliquefaction.org. Additionally, a supported modeling team was formed and has been working to define new liquefaction triggering and manifestation models. The models are approaching triggering and manifestation prediction using new methodologies to improve upon existing models.
