Investigation of the Shear Strength and Slope Stability of Turkish Municipal Solid Waste Composition

Abstract

Along with the developing world population municipal solid waste amount increases enormously. Uncontrolled waste storage, which is not in abidance with well defined engineering regulations endangers human life and cause economic loss. In this study, natural water content, organic matter content, specific gravity and pH values of the synthetic waste (with pre-determined compositions) and natural waste samples were investigated in laboratory conditions. The shear strength parameters of synthetic and natural MSW samples were determined by using a large scale direct shear test system. The slope stability analyses were conducted for present slopes at static and dynamic conditions and the factor of safety values were obtained. The obtained engineering parameters of Turkey MSW composition can be used in the design of safe and economical landfills in Turkey
