Registration has opened for the Deep Foundations Institute’s S3: Slopes, Slides and Stabilization Conference, planned for Aug. 3-5 at the Hotel Kabuki in San Francisco.

In a release, the DFI says the event is led by the group’s Deep Foundations for Landslides/Slope Stabilization Committee and the DFI-ADSC Anchored Earth Retention Committee, with contributions from seven additional DFI committees that support the subject matter. The two-and-a-half-day conference focuses on effective application of deep foundations, ground improvement, and soil mixing for stabilization of slopes and excavation support. Roberto Lopez, PE, chief engineer of Malcolm Drilling Company, serves as conference chair.

Invited speakers and experts will discuss the latest analytical and design methods, as well as practical applications. The event will highlight California case histories, with an emphasis on deep mixing and ground improvement techniques. In addition, three on-demand presentations are available to attendees.

This event features three invited speakers:

  • Ross Boulanger, Ph.D., PE, University of California–Davis, will overview seismic research efforts with a focus on current initiatives.
  • Rob Jameson, Malcolm Drilling Company, will review the last decade of deep mixing practices in San Francisco.
  • Mark Rice, Esq., McNeil Silveria Rice & Wiley, will address the legal and forensic considerations relative to landslides, causation and forensic analytics, as well as how post-slide investigations and legal resolutions can occur, with these steps often faltering due to inadequate initial investigations and “crime scene” capture.

The conference also features a 90-minute panel discussion and live webinar on appropriate modeling of groundwater in slope stability analyses. Erik Loehr, Ph.D., PE, of the University of Missouri–Columbia facilitates. Loehr serves as the trustee liaison for DFI’s Deep Foundations for Landslides/Slope Stabilization Committee. The webinar features providers of commonly used software packages discussing, analyzing and presenting solutions to the same real-world slope stabilization problem, and highlighting the influence of groundwater variations on the solutions.

The event includes an exhibit area where up to 30 DFI member companies have opportunities to showcase products and services.
