GSI offers webinar on in-situ stabilization of slopes using anchored geosynthetics

The Geosynthetic Institute (GSI) will offer a webinar on “In-Situ Stabilization of Soil Slopes Using Nailed or Anchored Geosynthetics,” on July 6, 2017, from 11:30 a.m. to 1 p.m. EDT.

The sliding of soil slopes in the form of localized landslides represents an annual loss of $2 to 5 billion in America, not to mention 25 to 50 casualties. Engineers analyze such failures; e.g., simplified Bishop for rotational surfaces and Corps of Engineers wedge method for translational surfaces. For existing slopes that cannot be completely reconstructed due to structures at the top or the toe of the slope, however, an in-situ remedial method is necessary. This webinar focuses on a geosynthetic placed on the surface of existing soil and then nailed or anchored into the soil beyond the potential failure surface. Originally called “anchored spidernetting,” the method provides several benefits, each of which increases the factor of safety, including increased soil friction, increased soil cohesion, nails penetrating the potential failure plane, and geosynthetic force added along the potential failure plane.

The webinar will be taught by Dr. Robert M. Koerner, professor emeritus of civil engineering at Drexel University and director emeritus of the Geosynthetic Institute.

Webinars cost $200.00 for GSI members and $250.00 for nonmembers. Successful completion of a multiple-choice test after the webinar carries 1.5 professional development units.
