A class of inhomogeneous shear models for seismic analysis of landfills

Seismic stability and permanent displacement of landfill along liners

“…Except for the pseudostatic method, the equivalent linear and nonlinear dynamic response analyses are also used to evaluate the seismic performance of landfills during earthquake [6][7][8] .…”

“…By integrating the equivalent acceleration in excess of the yield acceleration as a function of time, the permanent displacement of the sliding landfill can be estimated. The nonlinear dynamic response analyses proposed by Bray et al [7] and Gunturi et al [8] can consider the nonlinear properties of the waste and is mainly used at high levels of earthquake shaking. Rathje et al [9] analysed the seismic response of the landfill by the 1D wave propagation analysis program SHAKE91 and the two-dimentsional (2D) finite element program QUAD4M, and the results showed that 1D analysis could provide reasonable estimation of the seismic response and earthquake-induced permanent displacement for deep sliding surfaces, such as the one along the base liner.…”
