2D seismic response of landfills is explored in detail

in order to investigate stability of landfills at different intensity of earthquake shaking

as well as to evaluate the relative importance of different factors influencing the seismic response of landfills. The results indicate that the stability of landfill cover depends primarily on wastes properties

landfill heights

spectral characteristics of input motions

and site conditions; however

for base sliding case

the stability varies significantly due to the peak acceleration

period of input motions

and the basic period of landfill.
