Mechanical properties of Municipal Solid Wastes(MSW) and their influencing parameters were studied by using a series of triaxial compression tests and resonant column tests. The shear strength of MSW can be modeled by a bilinear failure criterion. As the unit weight increasing, cohesion and internal friction were increased linearly on semi-log scale. As the proportion of waste to soil increases, maximum shear moduli tend to decrease whereas minimum damping ratios increase. Shear moduli and damping of degradable waste are higher than those of non-degradable MSW.
