Webinar - Considerations of Induced Ground Deformations on Deep Foundations

Location: ASCE Continuing Online Education (All times are Eastern Time)
Date: November 27, 2017
Time: 11:30 AM – 1:00 PM

Deep foundations are designed to transfer load through unsuitable subsurface layers to suitable bearing strata.  When deep foundations are installed through a soil deposit undergoing consolidation, the resulting relative downward movement of the soil around piles induces “downdrag” forces on the piles.  If embankments are placed adjacent to deep foundations as in the case of bridge abutments, “lateral squeeze” effects can induce significant unbalanced lateral forces on deep foundations.  In the case of loose collapse-susceptible soils, the moisture induced soil collapse can have a significant lateral effect on deep foundations.  Seismic events can generate lateral spread and liquefaction related ground deformations.  Ground subsidence due to groundwater withdrawal can induced significant vertical as well as lateral force effects in deep foundations.  This webinar will discuss methods to evaluate such induced ground deformations in deep foundation designs.
