10th GGSS Round Table 2017 Conference Hall, UC Davis 10th March , 2017
The Geotechnical Graduate Student Society’s Round Table is turning 10 this year and we will be hosting our Annual event on Friday, March 10th, 2017 at the UC Davis Conference Center. The Round Table is an annual student showcase held at the University of California, Davis. Professionals from government and industry are invited to presentations and poster sessions by GGSS student members. The goal of the Round Table is to foster a connection with professionals so that researchers at UC Davis have an understanding of the needs of industry and industry is aware of the research projects at UC Davis. The event highlights include student presentations, poster sessions, a panel discussion, and social festivities.
GGSS Hosted it’s annual Fall Potluck on Saturday, October 22nd for students, faculty and friends of GGSS. Event Host Professor Boris Jeremic welcomed guests with a special brandy from one of his favorite collections. Guests poured in throughout the evening bringing a variety of wonderful dishes and desserts! In no time there was a gathering of around 50 geotechs with plenty of drinks, food, fun, and conversation. Event highlights included backyard socializing, Jenga, tree climbing, foosball, and of course tasty dishes on a wonderful fall night in Davis. The giant Jenga game was a hit with a record 32 floors built before collapse! Check out the picture gallery from the evening; you may even be able to spot a few Board members climbing the large tree in the backyard!
Thanks to Professor Jeremic and all of GGSS for another amazing potluck!
Thank you to all our sponsors, faculty, and student members for making Round Table a great success this year. It was great to share our research and to get your feedback and insights. We hope you enjoyed it as much as GGSS did!
We have many more photos from Round Table, as well as other GGSS events and announcements on the GGSS Facebook page. Please join the group to stay up to date with GGSS events, seminars, and short courses.
A BIG thank you to Kirk Ellison, Andrew Yeskoo and Adrian Crowther of ARUP for the excellent field tour on Friday January 31st. We visited the deep excavation of Salesforce Tower where we heard about the project from both ARUP and the contractor, Clark Construction. We discussed, in depth, the innovative barrette foundation elements being used to support the building core. Next, we visited the Park Tower site in the early phases of pile installation. Fresh samples of Franciscan Bedrock were passed around as we discussed the challenges it posed for design. Finally, the we were treated to a lesson in seismic structural design when we toured the under construction, 181 Fremont Tower. We witnessed the mega-column support system in the building’s lobby before going to the 10th floor for a discussion on the structural damping system and some excellent views of the under construction Transbay Transit Center. Here are few photos highlighting the tour.
Altamont landfill is nestled in the rolling hills of Livermore, CA and has been around since the 1980s. As all active landfills do, its been steadily growing to accommodate our daily wastes. Expansion of the Altamont landfill has converted a nearby rolling hills site (visited by GGSS in 2012) into a big excavation that we were able to visit. Thanks to Geosyntec, we got to have a close look at how the site is engineered to prevent watertable contamination while maintaining slope-stability. Special thanks go to Chris Hunt for providing the tour and the schematics seen below.
You can’t miss the entrance.
The meeting room had a to-scale version of the engineered foundation of the landfill showing the different layers.
Pumps used to extract leachate from the bottom-most permeable (gravel) layer of the liner.
Near the pumps was this minimap showing the layout of the tubes.

Geotextiles are sewn together by some pretty rugged grandmas.

We could see the bottom drain being built and shaped precisely* according to the engineered solution (*close enough).
