SUMMARY:
Results of laboratory tests are presented for the evaluation of
dynamic properties of Municipal Solid-Waste (MSW) from the Tri-Cities
landfill in the San Francisco Bay Area. Values of small-strain shear
modulus, Gmax, and the normalized shear modulus reduction and
material damping ratio curves are measured using large-scale cyclic
triaxial tests. The test results, which are considered representative
for depths up to 20 m, are used for investigating the dependence of
the waste material’s dynamic properties on specimen composition,
duration of confinement, unit weight of material, and loading
frequency.
