St. Louis, MO Workshop

St. Louis, MO Workshop

June 24, 2021 Drury Plaza Hotel- 380 Mulholland Drive, St. Charles, MO 63303

The workshop will present on how geohazards are an ever-present risk to the long-term performance of our critical infrastructure and how mitigation of these hazards is further challenged by budget, schedule, and access limitations. This workshop will present an introduction to geohazard identification and mitigation for highways, bridges, embankments, and sensitive structures. Multiple innovative construction methods will be presented with case studies highlighting cost-saving methods. Attendees will have the opportunity to participate in a hands-on demonstration of cutting-edge site reconnaissance technology utilizing drones and virtual reality software.

From this workshop participants should leave with a better understanding of:

• Identify common geohazards affecting critical infrastructure and understand their impacts.
• Implement geohazard mitigation techniques including drilled or launched soil nails, compaction grouting, and micropiles using FHWA guidance documents.
• Reduce project costs through rehabilitation of existing bridge abutments and retaining walls in lieu of replacement.
• Leverage drone technology to view and analyze a site during the design process.
• Utilize lessons learned from the Oso Landslide to better understand landslide behavior and mitigate geohazard risk.

Professor of Civil and  Environmental Engineering

Timothy D. Stark is a Professor of Civil and  Environmental Engineering at the University of Illinois at Urbana-Champaign with an expertise in Geotechnical Engineering. Dr. Stark has been conducting interdisciplinary research and teaching on the static and seismic stability of natural and manmade slopes, such as dams, levees, floodwalls, and waste containment facilities, railroad geotechnics, geosynthetics and geomembranes, soil liquefaction during earthquakes, and stabilization and behavior of dredged material containment areas. He has been involved in a number of projects on these topics, which has facilitated the transfer of his research results to practice. He is currently researching three-dimensional slope stability, inverse analyses of landslides, heating events in waste containment facilities, and jet grouting. Dr. Stark has received a number of awards for his research, teaching, and service activities including: 2019 George H. Norman Medal, ASCE, 2019; Technical Editors Award, ASTM STP 1605, ASTM, 2018; Spotlight Project at Illinois Transportation and Highway Engineering Conference, Illinois Center for Transportation, 2018; Best 2017 Paper Award, ASCE Journal of Performance of Constructed Facilities; Best 2015 Geosynthetics International Journal Paper; Best Research Paper Award, 14th and 13th International Railway Engineering Conference, Edinburgh, Scotland, 2017 and 2015; 2015 James M.

Keynote Speaker- Failure Mechanism and Runout of Oso Landslide

Professor Stark will present an update of his ongoing study of the 22 March 2014 Oso landslide near Oso, Washington.  This major and tragic landslide exhibited some interesting aspects of geo-mechanical behavior.  This detailed study is contributing to a better understanding of landslide triggering mechanisms and improved methods of hazard and risk assessment in the Stillaguamish River Valley. The on-going research is focused on landslide triggering and runout of the 2014 slide mass. In particular, Professor Stark will focus on the field and laboratory investigations, slope stability analyses, and triggering mechanism of the landslide.  He will also discuss the runout mechanism and distance that was investigated with Professor Oldrich Hungr of the University of British Columbia in Vancouver.
