Abstract
This paper extends a previously developed method of the writers by using a pseudostatic approach to conduct seismic stability analysis for potential translational failures of multilayer lined landfills. Assuming that the designed seismic coefficient,
ks
, is known, the factor of safety against translational failure for lined landfills can be calculated from the new developed equations. The critical interface with the seismic yield coefficient,
ky
, is generally located at different interfaces along the back slope and along the base. The failure surface is seen to transfer from one interface to another with changes of dimensions of the top width, depth, and front slope of the waste mass. Using this method, a waste filling sequence can be generated so as to maintain the
ky
-value above a stipulated value during landfill operations. It is important to ensure that the minimum
ky
-value at the critical interface is always equal to or greater than a targeted value during the waste filling sequence and after closure corresponding to the different geometric dimensions of the waste mass.
