Static and Cyclic Liquefaction of Mine Tailings and Soils | Short Course

This includes approaches in identifying and addressing brittle failure modes with conservative design criteria, independent of trigger mechanisms within the context of Requirement 4.6 of GISTM. 

Join our team of experts as they reflect and provide a forum for discussion of how these approaches can /are being applied at Southern African projects, in particular within the context of conformance with GISTM Principle 4, and Requirements 4.6 and 4.7.

 

COURSE PRESENTERS

Jonathan Bray, Ph.D., P.E., NAE is the Faculty Chair in Earthquake Engineering Excellence at the University of California, Berkeley. Dr. Bray is a registered professional civil engineer and has served as a consultant on important engineering projects and peer review panels. He has authored more than 400 research publications on topics that include liquefaction and its effects on structures, seismic performance of dams and slopes, earthquake ground motions and site effects, and earthquake fault rupture propagation. He created and led the Geotechnical Extreme Events Reconnaissance (GEER) Association. 

Scott M. Olson, PhD, PE is a Professor and Faculty Excellence Scholar in the CEE Department at the University of Illinois, where he joined the faculty in 2004. Prior to joining Illinois, Scott worked in practice for Woodward-Clyde Consultants and URS Corporation for nearly 8 years. Prof. Olson has researched static and seismic liquefaction for over 25 years and has been involved in dozens of research projects, consulting activities, and review boards involving geotechnical earthquake engineering; tailings dam engineering; in situ, laboratory, and centrifuge testing, soil-foundation-structure interaction; and paleoliquefaction and geohazards analysis. 

Dr. Jorge Macedo, Ph.D., P.E., is an Assistant Professor in the School of Civil and Environmental Engineering at the  Georgia Institute of Technology, where he joined the faculty in 2018. Dr. Macedo practiced as a geotechnical tailings engineer for six years (2008-2013), working on major mining projects in Peru, Argentina, Chile, and Brazil from conception to detailed engineering design, and he holds P.E licenses in California and Peru. Dr. Macedo’s main research areas are geotechnical earthquake engineering, mining geotechnics, and data-driven risk engineering applied to multi-hazards. He received the prestigious 2022 United States National Science Foundation CAREER award for his work at the convergence of tailings geotechnics and data science. Dr. Macedo is the founder and chair of the TAILENG (TAilings and IndustriaL waste ENGineering) center, which works on improving the resilience of infrastructure in the mining and power industries.
