In my previous entry regarding the Yeager airport landslide where I hypothesize for a possible shear zone somewhere near the foundation, I got some interesting comments from fellow engineers. In this entry I would like to clarify some issues. The hypothesis made about a shear zone was based on published information regarding intercalation of sandstone … Continue reading Yeager Airport Expansion slide additional comments
Recent news and photographs present the spectacular slide that occurred in the Yeager Airport Expansion Runway 5. The slide occurred in the South slope which was among the highest if not the highest (~74m) reinforced earth slope in the US. The project had received the award of Excellence – TenCate Geosynthetics in 2007 International Achievement … Continue reading What could have gone wrong in Yeager Airport Expansion slide?
This is a very controversial topic in which a straightforward answer is not possible. In this entry I would like to tackle some issues related to our own profession since we are responsiblefor the “acceptable” amount of investigation. Recently I attended the IAEG 2014 (Engineering Geology) conference in Torino. In this conference numerous interesting … Continue reading Geotechnical investigation data, always not enough?
The March / April Geo-Strata was almost entirely dedicated to the GAM (Geotechnical Asset Management) for transportation systems. It was very interesting to see how this concept is evolving in the broader field of Geotechnical Engineering and transportation infrastructures. This Geo-Strata feature is worth reading if you are interested in the future of Asset management … Continue reading Is geotechnical monitoring important?
