<p>This paper presents a methodology for designing side slope liner systems to accommodate downdrag due to waste settlement. Settlement and downdrag along steep-lined slopes in landfills and other waste or mining containment facilities (e.g. heap leach pads, ...

<p>Given the difficulties in identifying suitable sites for the establishment of new sanitary landfills, the extension of existing sites is considered more and more often as a solution. This increasing interest is also linked to the possibility of increasing ...

<p>This paper presents the perspective of one design practitioner regarding changes that have occurred in the industry over the past 25 years &ndash; particularly as related to the design of waste containment systems using geosynthetics. An effort has been ...

<p>A performance-based methodology for seismic analysis and design of the geosynthetic elements of waste containment systems, including landfills and heap leach pads, has been developed. The methodology offers a rational alternative to the current state of ...

<p>Several large-scale laboratory tests were conducted on multi interface geomembrane liner specimens to assess damage effects from static pressure, cyclic loading, and large displacement static shear. The specimens consisted of compacted subgrade soil, a ...

<p>Heap leaching is one of several leaching methods (in-situ leaching, dump leaching, pressure leaching and tank leaching) whereby metal and other ores are leached with various chemical solutions to extract valuable minerals. Commonly HDPE is used in the pad ...

This study includes an experimental investigation of the transient movement of water in unsaturated soil layers underlain by a geocomposite drainage layer (GDL) during cycles of infiltration and evaporation

This paper provides theoretical background, laboratory data and full-scale measurements useful in understanding the interaction between soils and geosynthetics under unsaturated conditions. It also includes an evaluation of the current state of knowledge regarding ...

<p>Ponds with exposed geomembranes on their sideslopes will be susceptible to wind forces, which must be resisted by properly designed anchorages at the slope crest. The most common anchorage is an earth-filled anchor trench. This paper describes improved ...

<p>The behavior of heat-tacked GCL seams under cyclic wetting and drying is examined. It is shown that the transverse shrinkage behavior of heat-tacked seams was similar to that observed in previous shrinkage tests performed on unseamed GCL. It is shown that ...
