Lecture

October 14, 2020 – Online David Paul delivers a virtual talk on the “Dam Safety program and positive impacts on critical infrastructure. The 2020-2021 DFI Traveling Lecturer, David Paul, presented a virtual lecture, “Forty Years of Dam & Levee Safety” to the ASCE New York chapter. The lecture focused on the failure of the Teton […]

June 8, 2021 – Online On June 8th at 12:00 PM Pacific, David Paul, P.E. presented his lecture “Emergency Repairs to the Mosul Dam: A High Risk Dam on Karst Foundation.” This lecture addressed the foundation engineering challenges related to karst geology and reducing the risk of failure of the dam which would be catastrophic […]

The failure of the Teton Dam in June 1976, prompted the U. S. government to enact dam safety legislation and a robust and active dam safety program to monitor the approximate 90,500 dams registered in the National Inventory of Dams (NID) maintained by the US Army Corps of Engineers.

On October 27th, join Dave Paul as he explores lessons learned from the Teton Dam failure with the ASCE Chicago chapter. This presentation will review geotechnical aspects of the failure and the cultural shift in dam engineering. This lecture will be delivered as a webinar.

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 liquefication and increase the foundation response stiffness of the mass of the material penetrated.

The presentation focused on how the development of more powerful and robust installation platforms has made it feasible to install cast-in-place piles into materials once considered too resistant for the system. This lecture reviews current installation platforms and tooling and presents case histories for installation in soft limestone, partially weathered rock, shale and glacial till.
