Case 9

Differential settlements of the top of the new landfill (blue layer), referring to the case reported just above. The differential settlement is provoked by the different stiffness characteristics of the 2 existing landfills. The landfill on the left is made of municipal solid waste (compressible and subjected to creep); the landfill on the right is made of waste assimilated to biologically inert sandy material. The rate of the deformation of the existing landfill slopes is different, and this generates the differential settlement.
