Purpose and Background

These presentations were recorded at the 2021 GI Web Conference.

This session will provide attendees with recent advances in Soil Improvement ranging from the immediately-applicable to technological advances that hold significant promise for improving civil infrastructure. Topics range from lateral spreading and stability of embankments supported on rigid inclusions, application of entrapped gas and polymers to mitigate the effects of earthquake-induced liquefaction and stabilize soil, to a case history describing the performance of a bridge supported on deep soil mixing during the M7.1 Anchorage earthquake. These lectures will be delivered by members of the Geo-Institute Soil Improvement Committee to strengthen the attendees’ confidence in existing technologies and showcase new techniques that will advance geotechnical practice.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Identify existing and novel ground improvements that can strengthen foundation soils against static and seismic loadings
• Leverage case history data for use in forward analyses of the stability of civil infrastructure
• Provide clients creative solutions to complex subsurface challenges
• Explain how full-scale geotechnical structures respond to various hazards
• Apply the latest in-situ testing and experimental techniques

Assessment of Learning Outcomes

Achievement of the learning outcomes will be assessed through a short post-test (true-false, multiple choice and fill in the blank questions).

Who Should Attend

Owners and operators of civil infrastructure, consultants, public agency staff, specialty contractors.

Outline

• Performance of the Wet Soil Mixing-Supported West Dowling Bridge during the 30 November 2018 Anchorage Earthquake (Presented by Armin W. Stuedlein, PhD, PE, M.ASCE).
• How burping bacteria can mitigate earthquake induced liquefaction: Distribution and durability of entrapped gas in the subsurface
• Lateral spreading and the stability of embankments supported on unreinforced rigid columns
• Evaluation of Resin Injection for Liquefaction Mitigation Using Blast-Induced Liquefaction Testing lignin to stabilize soils and its water resistance

How to Earn your CEUs/PDHs

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 365 days of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
