<br />SIMPLIFIED SEISMIC DESIGN PROCEDURE FOR
<br />GEOSYNTHETIC-LINED,SOLID-WASTE LANDFILLS
<br />ABSTRACT:Thispapercriticallyreviews seismic designpractices inlightoftheobserved
<br />performance oflandfillsduringrecentearthquakes. Developments intheseareas aresumma-
<br />rized as follows: earthquake ground motions, dynamic waste fill properties, dynamic re-
<br />sponses of geomembranes and their interfaces, nonlinear dynamic response analysis, and
<br />seismic stability evaluation. A newly developed simplified seismic analysis procedure that
<br />requiresthemostcriticalfactorsbeaddressedduringaseismicperformanceevaluationispre-
<br />sented. The underlyingseismic analysis procedure has been validated against observed per-
<br />formanceoflandfillsshakenbythe1989LomaPrietaand1994Northridge,Californiaearth-
<br />quakes. Theprocedure iscomprehensive inthatit requires: (i)characterization ofthedesign
<br />bedrock motions interms ofintensity,frequency content, andduration; (ii)estimation ofthe
<br />seismic loading at the base and coverofthelandfill; (iii)evaluation ofperformance interms
<br />ofseismically induced permanent deformations; and(iv)appropriate engineeringjudgment.
