Geosynthetics as Solution to Geotechnical Problems in a MSW Landfill

摘要

Scarpino landfill is the biggest mountain-located landfill in Italy, and the second one for waste material placed (aboutrn9,000,000 m~3). Recently, due to some changes in environmental regulations and to allow the expansion of the landfill inrnits central part, some stabilization works, together with the definitive closure at the toe of the landfill, have becomernnecessary. The authors are involved in the design and in the work direction of the stabilization works, up to date almostrnfinished, and of the capping, now in execution.rnThe article describes the applications of geotextiles and geomembranes in the stabilization works (that is reinforcedrnearth), in the replacement of the old bottom lining system and in the final capping, focusing on the problems related tornthe particular morphology and topography of the site, that have required the use of geosynthetic materials instead ofrnearth materials.
