Geo-Institute Case Histories Night with Dr. Jean-Louis Briaud 

The St. Louis Geo-Insitute Chapter of ASCE presents “Behavior of Two Mats under Heavy Load – Washington Monument and San Jacinto Monument” and Student Projects. Dr. Jean-Louis Briaud, 2015-2016 Cross USA Lecturer, will present two case histories. Student projects will also be presented.

Doors open at 5:00 PM for check-in and registration, with student posters on display. 

Buffet dinner will be served at 5:30 PM. 

Student presentations will begin at 6:00 PM. 

Dr. Briaud's case histories presentation will begin at 6:30 PM.

Registration deadline is Friday, April 22, 2016. ASCE is charged for all reserved meals. If you've signed up and can't make it, please cancel by 04/22/2016 or we will have to charge you for the meal.  

The lecture investigates the geotechnical behavior of two large mat foundations over several decades of time. The first case history is the foundation of the Washington Monument in Washington DC completed in 1885 and the second case history is the foundation of the San Jacinto Monument in Houston, Texas completed in 1936. Both mats are about 38 m by 38 m and settlement records are available. Calculations performed with respect to depth of influence, stress increase with depth, consolidation settlement, and ultimate bearing capacity are presented. Additional considerations include the influence of soil heterogeneity and underpinning. Lessons learned from the behavior of these two mats are drawn and recommendations are made for the geotechnical aspect of mat foundations.
