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.

Workshop introductions and agenda
Demo of the Hololens2 from Clirio & BCG Engineering
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.
