Slope Stability of Municipal Solid Waste Landfills under Seismic Loading

Design of municipal solid waste (MSW) landfills requires a considerable attention due to the undesirable environmental and socio-economical impact of a potential failure. Furthermore, recent research and engineering practice experience in developed countries characterized by high seismicity, like U.S.A and Japan, has shown that MSW landfills are vulnerable to the seismic threat. Despite the viv...

Slope Stability Analysis Under Combined Failure Criteria

Strength reduction finite element method (SRFEM) has been widely used to analyze the slope stability. Strength Reduction Factor (SRF) is yielded as the slope Factor Of Safety (FOS) when a running-though shear failure zone comes into being, in which the Plastic Element EQuivalent strain (PEEQ) is employed as the judgment of shear failure initiation in this paper. Moreover, the filed variable is ...

Effect of Different Groundwater Levels on Seismic Dynamic Response and Failure Mode of Sandy Slope

Heavy seismic damage tends to occur in slopes when groundwater is present. The main objectives of this paper are to determine the dynamic response and failure mode of sandy slope subjected simultaneously to seismic forces and variable groundwater conditions. This paper applies the finite element method, which is a fast and efficient design tool in modern engineering analysis, to evaluate dynami...
