The University of Delaware received a $200,000 Engineering Research Initiation (ERI) award from the National Science Foundation (NSF) under the Engineering program (CFDA 47.041). This project grant aims to advance the state of knowledge and practice regarding the evaluation of liquefaction-induced ground failure and its effects on infrastructure. Key objectives include:
-
Documenting and characterizing subsurface features through advanced field exploration techniques to identify mechanisms responsible for the formation or abatement of liquefaction ejecta at sites where conventional procedures have misestimated its severity.
-
Validating dynamic nonlinear effective-stress models for stratified silty soil deposits and developing fundamental insights into the cyclic response of these deposits through advanced laboratory testing.
-
Developing recommendations for assessing the vulnerability of soil deposits to the formation of liquefaction ejecta.
This research seeks to improve resilient engineering design and practice by generating new knowledge about liquefaction and its consequences. The project will run from October 1, 2024 to September 30, 2026 and involves collaborations with geotechnical engineers in the U.S. and New Zealand to implement the research findings in practice.
