Centrifuge Modeling of Solid Waste Landfill Systems—Part 2: Centrifuge Testing of Model Waste

This paper presents the use of the model waste developed in the companion paper, “Centrifuge modeling of solid waste landfill systems—Part 1: Development of a model municipal solid waste,” in centrifuge testing. Two centrifuge tests were performed using the model waste to understand the static and dynamic behavior of municipal solid waste (MSW) landfills. First centrifuge test demonstrates the use of model waste to study the settlement profile in a landfill. In the second centrifuge test model earthquake loadings were applied to the model waste to investigate its dynamic behavior. The results were used to obtain shear modulus reduction and damping curves of the model waste. These curves were shown to match with those reported for MSW validating the use of model waste to study the seismic behavior of MSW landfills.
