This seminar will be split into sections throughout the course of the day addressing the following topics:
- Tensile strength (wide-width index tests and isochronous load-strain performance tests), manufacturers test data.
- Soil-geosynthetic interface strength (direct shear and pullout bond coefficients).
- Material durability.
Case Study I:
- Arrangement of the geotextiles, instrumentation, and post-construction behavior in Rainier Ave. Wall, Seattle.
- Overview of external and internal stability analysis in design (FHWA, AASHTO, BS 8006).
Case Study II:
- NGI Sloped Wall, Oslo (arrangement of the geogrids, instrumentation, and long-term (10 years) field monitoring of post-construction load-strain-temperature data).
- Allowable tensile strength.
- Required tensile strength.
- Vertical spacing of reinforcement.
- Length of reinforcement.
- Seismic loading issues.
A discussion and course summary will be held after all topics have been covered.
Jonathan Fannin, PhD, P.Eng., is a Professor of Civil Engineering at the University of British Columbia (UBC). He has been involved with teaching, consulting, and university-industry research on geosynthetics for 20 years, in Europe, North America, and South East Asia. He is a recipient of the International Geosynthetics Society Award for contributions of research to engineering practice. His professional activities have included Vice President of the North American Geosynthetics Society, and Chair of the Canadian Geotechnical Society, Geosynthetics Division. He has delivered continuing education short courses in Canada, the USA, and Europe. He has twice received a UBC Killam Prize for teaching excellence, and more recently received the APEGBC President’s Teaching Award.
Robert (Bob) Holtz, PhD, P.E., is a Professor Emeritus of Civil Engineering at the University of Washington in Seattle. He is a Past President of the North American Geosynthetics Society, and of the ASCE Geo-Institute. His work on geosynthetics spans more than 35 years, and his research has been sponsored by FHWA, US Air Force, Washington State DOT and several geosynthetics manufacturers. He is author, co-author, or editor of 21 books and book chapters, including Introduction to Geotechnical Engineering (with W.D. Kovacs, 1981), FHWA Geotextile Engineering Manual (with B.R. Christopher, 1988), and Geosynthetic Engineering (with B.R. Christopher and R.R. Berg, 1997). Bob has taught many short courses and workshops on geosynthetics, including more than 50 FHWA 3-day courses on Geosynthetics Engineering. He is a Fellow, Life, and Distinguished Member of ASCE, Past President of NAGS, and a past member of the IGS Council. He is currently US Secretary for the ISSMGE and the Geo-Institute of ASCE, and on the Board of the ISSMGE.
