Stability of Geosynthetic Lining Systems is, for a geotechnical standpoint, a complex matter. Three geomechanical questions were identified: sliding of the geosynthetic lining system on slope, pull-out strength of the geosynthetic anchorage at the top of the slope, rain erosion of the cap cover. Research programmes carried out in France on these topics, , are presented. Use of laboratory facilities (mainly different Inclined Planes) and large scale experimentations on actual slopes is… Expand
Interface behaviour of geosynthetics in landfill cover systems under static and seismic loading conditions
Modern landfills are equipped with multi-layered liners, including geosynthetic-geosynthetic and soil-geosynthetic interfaces. The interfaces represent weakness surfaces where the shear strength is aExpand
Frictional characteristics of geosynthetic–geosynthetic and geosynthetic–soil interfaces determined by the inclined plane apparatus
Abstract The problem of managing the unneeded and unusable materials is a serious challenge for modern societies. The progress of civilization is accompanied by an increase of the human population.Expand
Geosynthetics anchorage with wrap around: experimental and numerical studies
ABSTRACT: Geosynthetics are used as reinforcing elements in a wide variety of structures: reinforced slopes and walls; embankments on soft soils; piled embankment; reinforcement in the base layers ofExpand
Interface shear: Towards understanding the significance in geotechnical structures
It is well known that low strength natural materials under foundations and in slopes can cause bearing capacity and slope failures. With the increased use of manufactured materials such as HDPEExpand
Interface behaviour and stability of geocomposite drain/soil systems
Landfill covers are designed as impermeable caps on top of waste containment facilities after the completion of landfill operations. Geocomposite drain (GD) materials consist of a geonet or geospacerExpand
Shear Strength of Unsaturated Soil-Geotextile Interfaces
Geotextiles are widely used in various applications including earthen structures, which are often built in unsaturated soil conditions. The design of these earthen structures is often dominated byExpand
Performance Based Design for Seismic Design of Geosynthetics-Lined Waste Containment Systems
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 methodologyExpand
