Dimensional Stability Of Geosynthetic Clay Liners In Landfill Applications, Gregory R. Olsen
Dimensional Stability Of Geosynthetic Clay Liners In Landfill Applications, Gregory R. Olsen
Master's Theses
An investigation was conducted related to the dimensional stability of geosynthetic clay liners (GCLs) in landfill applications. Multiple occurrences of panel separation of overlap seams in GCLs have been documented; however, explanation for the relative contribution of various mechanisms causing shrinkage has been limited. A systematic test program was conducted to determine the effects of a variety of conditions on GCL dimensional stability.
Effects of initial moisture content, permeant type, and overburden pressure were tested by subjecting various GCL products to wet-dry cycles and measuring the dimensional change with each cycle. Different GCL types were each tested under various combinations …
