Evaluating the Dynamic Characteristics of Municipal Solid Waste for Geotechnical Purpose

By B. P. Naveen, T. G. Sitharam, P. V. Sivapullaiah

An ability of engineer to evaluate the likely municipal solid waste (MSW) landfills for a seismic performance is limited currently by the lack of reliable data on the stress dependent dynamic properties of MSW. The required dynamic properties of the waste materials include the:

  • The MSW unit weight profile.
  • Small –strain shear modulus(Gmax) or Shear wave velocity (Vs)
  • The stress dependent normalized shear modulus reduction (G/Gmax) and material damping ratio relationship.
Several attempts made in the past to determined the dynamic properties of MSW. The following is the summary of the earlier work carried out.
