Shrink swell soil causes significant pressure on foundations, roads, and other infrastructure, with a high expansion volume when wet and high shrinkage when dry. TRB hosted a webinar on Tuesday, March 12, 2024 from 11:00 AM to 12:30 PM Eastern that shared innovative findings and the state of practice for foundations in shrink swell soil. Presenters shared research findings on the uplift of drilled shafts and pressure on retaining walls due to these soils. Presenters also discussed the pile load transfer mechanism in unsaturated shrink swell soil and practical aspects of deep foundation design.
This webinar was sponsored by TRB’s Standing Technical Committee on Foundations of Bridges and Other Structures.
