Webinar – Reliability Analysis of Landfill Slopes – June 11

News | May 28, 2024 | By:

The Fabricated Geomembrane Institute (FGI) is presenting the webinar – Reliability Analysis of Landfill Slopes – on June 11 at noon CDT. Pre-recorded viewings are:

June 12, 2024 at Noon AEST (Pre-recorded – Australia)

June 12, 2024 at Noon CAT (Pre-recorded – South Africa)

June 12, 2024 at 5 p.m. JST (Pre-recorded – Japan)

The presenters are Timothy D. Stark, Ph.D., P.E. University of Illinois at Urbana-Champaign and Jiale Lin, Ph.D. University of Macau. The webinar is free to industry professionals and students, a 1.0 PDH is available, and you can register here.

This webinar will propose a reliability analysis for geosynthetic-lined landfill slopes that employs the procedure in Duncan (2000) and a variation of 5-15% in the input parameters to assess the sensitivity of each parameter. Additionally, a random distribution is introduced to accommodate uncertainty in: (1) shear displacements induced, and thus mobilized interface strength, in a bottom liner system, (2) waste unit weight, and (3) leachate level in the landfill to assess their impact on probability of failure.

Dr. Timothy Stark is a professor in the department of civil engineering at the University of Illinois at Urbana-Champaign. Dr. Stark has been conducting interdisciplinary research on geosynthetics, and in particular geomembranes, for the last 25 years. This includes his research on the installation and long-term durability of geomembranes and other geosynthetics in geo-environmental and seepage applications. He is the technical director of FGI, which is an industry sponsored research organization investigating the advantages and disadvantages of geomembranes for containment and seepage applications.

Dr. Jiale Lin completed his Ph.D. in geotechnical engineering at the University of Illinois at Urbana-Champaign in 2022 and is currently a post-doctoral research assistant at the University of Macau. The focus of his Ph.D. research was the stability of geosynthetic-lined slopes, which involved numerical modeling and laboratory testing of geosynthetic interfaces. He has published a number of journal papers on these topics. Visit the FGI Website for more info and upcoming events.
