2019-20 DFI Traveling Lecture at ASCE MET Section (sponsored by RA Engineering LLP)

March 12, 2020 – Online

The 2019-20 DFI Traveling Lecturer Willie M. NeSmith, P.E., will be delivering a presentation on “The Application of Drilled Displacement Elements for Liquefaction Mitigation and Foundation Improvement” for ASCE, sponsored by RA Engineering LLP.

The presentation examined 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 liquefaction 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.
