Speaker: Prof. Edward Kavazanjian, P.E., NAE

Edward KavazanjianFactors that must be considered in seismic design of geosynthetic waste containment systems include the seismic performance objectives, the potential of detection and repair of earthquake-induced damage, modification of earthquake ground motions by the waste mass and by interaction between the waste mass and geosynthetic elements of the containment system, and the fragility of those geosynthetic elements. Unconditional stability may be a difficult performance objective to satisfy in areas of high seismicity. While repairable damage may be considered acceptable performance, damage may be difficult to detect and repair, mandating a higher performance standard than if damage is easily detected and repaired. Furthermore, the allowable strain in a geosynthetic containment system designed to resist an earthquake with no damage may be significantly less than the geosynthetics yield strain.

Learning Objectives
Participants of this course will learn how to:

  • Establish rational seismic performance objectives for geosynthetic containment system elements
  • Identify when pseudo-static limit equilibrium and Newmark-type seismic performance analyses are appropriate for use in design
  • Recognize containment system details particularly susceptible to earthquake-induced damage
  • Implement measures that mitigate the potential for earthquake-induced damage togeosynthetic containment system elements

Speaker: Boyd Ramsey

Boyd RamseyThis special session has been developed by the International Geosynthetics Society (IGS) Technical Committee on Barriers.

Geosynthetics have demonstrated excellent performance as barrier materials in multiple applications around the world. In nearly every case, geosynthetics constructions offer four primary benefits:

  • Durability: The materials have excellent demonstrated lifespan and strong scientific projections of future lifespan.
  • Consistency: The materials are less variable than traditional construction materials (sand, soils, clay, gravel, etc.) and there are established methodologies for manufacturing quality control.
  • Barrier Performance: Geosynthetics offer improved barrier performance, shorter construction times and allow for designs and systems that simply could not be created with traditional materials.
  • Sustainability: In addition to the improved barrier and direct environmental benefits, geosynthetics offer reduced environmental impact, energy consumption, and reductions in greenhouse gas emissions, reductions in transportation operations, reduced insurance health and safety burdens

Session includes case histories and examples of best practices, with particular attention to projects, papers and applications that combine all four of these principle attributes.

Speaker: Prof. R. Kerry Rowe, P.E.

Kerry RoweThere is now 20+ years’ experience with the use of geosynthetic clay liners (GCL) either alone or in combination with a geomembrane in caps/covers and base liners. However, there have also been problems. This lecture seeks to help the engineer design and construct liners that will give good long-term performance. The lecture begins with basic concepts of what makes these liners effective. It discusses factors that affect the performance of GCLs, including: the effect of method of GCL manufacture and how this affects GCL performance in different applications; designing to deal with cation exchange; interaction between the fluid to be retained and the GCL; internal erosion; what makes for good GCL overlaps/seams; effect of subgrade on GCL performance; minimizing leakage through GCL and composite liners, and effects of leaving composite liners exposed. The lecture illustrates points with reference to field performance at a number of well-documented cases where GCLs were used either alone or as part of a composite liner. The lecture will benefit everyone from the new engineer to the most-experienced practitioners by starting with the basics (no assumed knowledge) and building logically and clearly through what we have learnt over the past 25 years. The lecture will present some of the latest findings and advances in understanding on the topic and lessons learnt.
