Stability Analysis of Landfills in Seismic Area
The design of landfills includes stability analyses based on appropriate mechanical characterization of soil and Municipal Solid Waste (MSW). Particular attention must be devoted to MSW landfills in seismic areas, where the waste fill and liners can be damaged by the seismic loading, as documented by recent earthquakes. Then, to analyze the seismic stability of landfills, in addition to the dynamic characterization of soil, the dynamic properties of MSW are also required. With this aim, in situ and laboratory tests can be performed and static and dynamic properties can be evaluated. In this paper the results of a geotechnical investigation carried on the Cozzo Vuturo landfill in the Enna area (Sicily, Italy) are reported and analyzed. In particular, Seismic Marchetti Dilatomer Tests (SMDT) have been carried out for the seismic characterization of waste and the test results are used to derive shear wave velocity profiles and dynamic properties of the deposited waste materials. The behavior of the MSW landfill subjected to earthquake loading is modeled in terms of displacement analysis.
