Geotextile-Encased Stone Columns for Railway Passage MSE Walls

Cobramseg is a biennial geotechnical engineering event in Brazil that combines multiple national and international engineering conferences. It’s one of South America’s most important engineering gatherings. At the 2016 edition, Ana Carolina Portela Costa, Ary Franck Baia Cordeiro, Leonardo Campos Dias, and Julián Buriticá García of Dinamiza Consultoria e Engenharia Ltda and Renato Pinto da Cunha o... »

MSE Wall Failures vis-à-vis the Lack of Geotechnical Filters

By Dr. Robert M. Koerner – Since 2001, the Geosynthetic Institute has accumulated data on failures of geosynthetic-reinforced mechanically stabilized earth (MSE) retaining walls. Our MSE wall failures database presently has 301 cases, of which 191 (63%) have been caused in whole or part by water within, or adjacent to, the reinforced soil zone. We sincerely hope that our past writings and webinars... »

Geosynthetic Reinforcement for Wind Energy

Subsidies and federal energy policies get most of the headlines, but with the increasing size of wind turbines and the scale of wind farms, few sites can be developed without soil reinforcement technologies. Geosynthetics provide the stable base for construction works and long-term access on wind energy sites. On-shore wind turbine hub heights increasingly crest 100m, and some are approaching 150m... »

Hydraulic Engineering Solutions Seminar, July 14

Waterways are dynamic environments. Strong hydraulic engineering solutions are needed to create resilient infrastructures that minimize environmental impact, control costs, and provide long-term performance. On July 14, Maccaferri will host  an exclusive breakfast seminar (7:30 am – 11:00 am) in Gaithersburg, Maryland focused on the application and design of hydraulic solutions. The seminar is fre... »

The Geotechnical Poetry of Mary Nodine

Geotechnical engineering requires a lot of waiting. You wait on calls, test results, the weather. You wait on a construction activity to finish, on software to complete extremely complex models, on site assessments to be signed off on. You wait in labs and airports, on calls, in lobbies. So what to do with all that waiting? Sometimes, you let the mind wander. It may just take you to geotechnical p... »
