Abstract

Multiple lines of evidence are used to draw conclusions concerning the shear strength of degraded municipal solid waste (MSW). Interpretation of the accumulated evidence leads to the conclusion that for conventional "dry" landfills the shear strength envelopes commonly used in practice provide reasonable strength values for circular and non-horizontal failure surfaces even for old landfills where the waste may be in a relatively advanced state of degradation. However, for horizontal failure surfaces in conventional landfills that may not engage the fibrous waste components, for landfills where mechanical pre-processing has been used to reduce waste constituent size and facilitate degradation, and for bioreactor landfills, a strength envelope characterized by zero cohesion and an effective friction angle of 30 degrees appears to provide a conservative representation of degraded MSW shear strength.
