Abstract: Seismic stability and permanent displacement of cover soil in a solid-waste containment system are performed using the discontinuous deformation analysis (DDA). The effects of the inclination angle, the friction coefficient of the soil-geosynthetic interface, the length and thickness of cover soil and the earthquake strength on the stability and permanent displacement are discussed. The failure mechanism of cover soil in a solid-waste containment system is also discussed. Numerical simulations are done to testify and compare the two-part wedge theory proposed in literature [1]. Parametric study indicates the applicability of the two-part wedge theory. At the same time the seismic design suggestions are proposed.

Key words: landfill cover system, stability, permanent displacement, discontinuous deformation analysis, slope
