Thermomechanical Behavior of Saturated Geosynthetic Clay Liners
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 139, Issue 4
Abstract
The aim of this study is to assess experimentally the volume change behavior of geosynthetic clay liners (GCLs) under elevated temperatures. Such elevated temperatures can be generated in landfills as the result of biological decomposition of organic matter in municipal solid waste. A modified consolidometer capable of handling temperatures up to 60°C was utilized for this purpose. A series of thermomechanical consolidation tests were performed on two different GCLs at different elevated temperatures, varying from 20 to 60°C, and different vertical stress levels (50, 100, and 150 kPa). The results show that the thermally induced volume change is stress dependent. A preliminary conceptual explanation for this behavior is introduced and discussed in this study.
