<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>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 review of 92 heap leach projects from 15 countries provides a starting point for a series of experiments, at 22 &deg;C and a vertical pressure of 2000 kPa, to examine short-term puncturing and the development of geomembrane strains that could affect longer-term ...

<p>Results from two sets of laboratory test programmes on sand-salt mixtures in which the salt fractions, of different amounts and size, are dissolved are brought together to gather insight into the mechanics of mass loss and its controlling factors. The test ...

<p>For the last three decades, high density polyethylene (HDPE) geomembranes (GMBs) have played a crucial rule as the primary barrier in municipal solid waste (MSW) landfills. In parallel, there have been extensive investigations into the service life of HDPE ...

<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>The subject of this paper is exposed-geomembrane-lined ponds whose leakage to the environment is highly undesirable. Such ponds are actually quite common in industrialized settings, and they form an important part of the operating infrastructure of many ...

<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 ...

<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 ...
