Chapitre VII: Barrières de confinement des centres de stockage des déchets

ABSTRACT A correct waste containment philosophy consists of: (1) optimization of the landfill location, (2) construction of high performance lining and capping systems, (3) optimization of waste storage, (4) short and long term careful monitoring, and (5) a convenient re-use of the landfill area after closure. The geotechnical engineer has strong skills about all the aforementioned topics but in particular can effectively deal with the design, construction quality control and monitoring of the lining and cover systems, the waste storage and compaction procedure, and the foundation and improving treatments for constructions above waste deposits. Due to the large number of geotechnical aspects involved into the above listed issues, only the lining systems for landfill base and sides are illustrated in this chapter. These topics have been developed referring to their background, recent advancements and new trends. In particular, the fundamentals of updated design procedures are illustrated with particular reference to conceptual and practical modeling and assessment of related input parameters. Moreover the main literature references are provided.
