Abstract

The compression characteristics of degraded municipal solid waste were studied by using large scale compression apparatus. The municipal solid waste materials were divided into three parts which were: easily degradable, difficult to degrade, and incompressible solid waste material in a geo-environmental laboratory. Three mixture proportions, three different initial densities, four different degraded times, four different pressures, and eight different compression times were selected for the compression test. The test results show that: (1) The total strain of degraded municipal solid waste increases with vertical pressure, and the relationship can be described as a logarithmic model; (2) The total strain of degraded municipal solid waste increases with initial density, and the relationship can be formulated as a linear relation; (3) The density of degraded municipal solid waste increases with degradation time, and the relationship can be expressed as a logarithmic model.
