GIGSO members attend the 2019 Northwest Geotechnical Graduate Student Symposium in University of Washington on April 12th, 2019. Professor Armin Stuedlein, student member Margaret Exton, Yingqing Qiu, Amalesh Jana and Nicolas Mattews present thier research during the symposium.
Interested geotechnical engineering students from Oregon State University (OSU) had the chance to visit two existing single track train tunnels along the Pacific Coast of Oregon just south of Florence, OR, USA earlier this year on February 1st, 2019. A summary of our experience and some pictures can be found by following this link.
A large group of OSU students and GIGSO members were able to visit the Bellevue Tunnel, which was under construction. The City of Bellevue - and the tunnel is located east of Seattle, Washington. The tunnel was excavated with SEM - sequential excavation method - with diggers, excavators, steel sets, and sprayed concrete. A summary of our experience and some pictures can be found by following this link.
GIGSO alumnus, and recent Oregon State M.S. graduate, Youssef Bougataya was selected as the winner of the Deep Foundations Institute (DFI) Educational Trust 2016 Student Paper Competition. Youssef's paper, titled "Region Specific Calibration of Resistance Factors for Use with Static and Wave Equation Analyses of Driven Piles", can be found in a future issue of the DFI Journal, and more information on the achievement may be found here.
On June 20-23, 2016, GIGSO member Stephie Lange had the opportunity to attend a short course, titled "Tunneling Fundamentals, Practice, and Innovations", at the Colorado School of Mines. The course provides a setting for experts in the tunneling field to share knowledge with industry professionals, and is offered on an annual basis. Stephie has been kind enough to write up a summary of her experience, which can be found by following this link.
Our club is pleased to announce that the prediction of master's student and GIGSO member, Youssef Bougataya, and undergraduate senior, Nathan Jones, has won the prestigious Mohr's Circle trophy by placing first in the 2016 Geo-Institute GeoPrediction competition. More details on this year's project, and competition rules, can be found here, while a nice writeup by the College of Civil and Construction Engineering may be found here.
On November 1-4, 2015, the city of Christchurch, New Zealand hosted the 6th Interntional Conference on Earthquake Geotechnical Engineering. Participants from Oregon State University were GIGSO members, Stephie Lange and Kengo Kato, as well as College of Engineering Dean, Scott Ashford, and School of Civil and Construction Engineering faculty, Michael Olsen, Armin Stuedlein, Ben Mason, and Daniel Gillins. Stephie has provided a summary of her experiences at the conference, and New Zealand in general, which can be found by following this link.
Andrew and Trevor received first place at the GeoPrediction Competition at Geo-Congress 2014! They most accurately predicted results from a geotechnical case history. Andrew and Trevor presented their results to conference attendees and produced a poster describing their award winning analysis. Overall 26 international teams were involved in the competition for this years Geo-Congress conference held in Atlanta, Georgia.
Andrew and Trevor would like to thank Dr. Armin Stuedlein, P.E., their graduate and undergraduate classmates, reviewers, OSU CCE and everyone else typically thanked by Hollywood award winners (with a Corvallis alpha angle of inclination of course).
In March 2014 the Civil Engineering-Geotechncial graduate students participated in the OSU School of Civil and Construction Engineering and School of Mechanical, Industrial and Manufacturing Engineering Graduate Student Research Expo at the Double Tree by Hilton in Portland Oregon. This provided an opportunity to present ongoing research to industry professionals, prospective graduate students and faculty of the two schools. There was a competetion of the top-ranked presentations and posters, judged by the attending industry professoinals. Drew Strahler took home the overall 3rd place prize for his research regarding mechanically stabilized earth (MSE) walls...take a look at his poster below!
