    Abstract

    Little is known about the geotechnical properties of waste materials, either in their initial state or after various levels of decomposition. Such information is critical when assessing the stability of waste fills during placement, and at the time of closure and rehabilitation. Recent efforts to address these particular concerns remain in developmental stages, and practical problems persist with regards to in-situ or laboratory scale testing. In addition, the complexity of the problems is increased due to the variability in composition, placement conditions and levels of decay of the various constituents of the waste fills. This paper describes laboratory experiments that were conducted to establish relevant shear strength parameters for municipal solid waste. The shear strength testing was accomplished by using a large direct shear apparatus specifically designed and developed for the purpose. Results from the laboratory testing program are presented and discussed in the context of their potential use in conducting geotechnical stability analyses.
