Title: Seismic Response of Landfills: In-Situ Evaluation of Dynamic Properties of Municipal Solid Waste, Comparison to Laboratory Testing, and Impact on Numerical Analyses (NEES-2010-0920)
Year Of Curation: 2014
Description: The increasing amounts of municipal solid waste (MSW) generated every year are, in their majority, landfilled. Modern (since the 1990s) MSW landfills are environmentally sensitive, sophisticated facilities and are similar in size to large dams. Recent U.S. earthquakes (e.g. 1994 Northridge Earthquake) highlighted the potential seismic vulnerability of MSW landfills. Excessive movement during shaking may damage the landfill?s containment or cover system or cause stability failures. The impact of such failures on the environment can be devastating. The use of accurate and representative dynamic properties of Municipal Solid Waste is a requirement to reliable seismic engineering analyses and design, but our understanding of the dynamic properties of MSW is rudimentary and lacking.
