Description
In this in-person, half-day seminar, members of one of the Next Generation Liquefaction (NGL) model development teams, known as the SMT, will highlight the main outcomes of a project jointly supported by the U.S. Nuclear Regulatory Commission (NRC) and the U.S. Bureau of Reclamation (USBR) to use the extensive NGL project’s case history database to develop a suite of models for the probabilities of liquefaction susceptibility, triggering, and ground surface manifestation.
This presentation will:
- Describe vetted models now available for application in practice, which are documented in a peer-reviewed NRC report.
- Define technical terms that comprise the framework for liquefaction analysis (susceptibility, triggering, manifestation), present the motivation for the work, and describe our research approach.
- Identify challenges inherent to the traditional critical layer framework used in the development of most existing liquefaction triggering models.
- Describe the application of laboratory data to inform relationships for liquefaction triggering resistance.
- Describe case history data interpretation, including layer identification from cone penetration test (CPT) data, layer property characterization, and ground motion estimation.
- Describe model development using a profile-based regression framework that separately considers the mechanisms of liquefaction susceptibility, triggering, and manifestation.
- Present example applications of the models and contrast the results with those from legacy models.
