2019-20 DFI Traveling Lecture at ASCE and Geo-Institute Seattle Geotechnical Section

February 27, 2020
Executive Inn by the Space Needle
Seattle, Washington
The 2019-20 DFI Traveling Lecturer Willie M. NeSmith, P.E., will be delivering his presentation on the Application of Drilled Displacement Elements for Liquefication Mitigation and Foundation Improvement for the ASCE and Geo-Institute Seattle Geotechnical Section.

The presentation will examine the increase in density in the vicinity of drilled displacement piles when they are installed in materials that exhibit granular behavior. The increase is most pronounced in loose to medium dense materials and can be utilized to mitigate liquefication and increase the foundation response stiffness of the mass of the material penetrated. Case histories are presented wherein ground improvement elements were installed using drilled displacement pile processes to mitigate liquefaction and increase allowable foundation loading.
