ASPECTS OF LANDFILL DESIGN FOR STABILITY IN SEISMIC ZONES

In areas where seismic events occur frequently, the structural stability of waste disposal facilities may be threatened. Current design methods for landfills were developed under the assumption of static loading conditions. In seismically active areas, design and other ancillary measures need to be implemented to raise the factor of safety for the long-term stability of landfills. In this article, the seismological and geotechnical factors that control the risk of landfill damage are briefly discussed. A zonation scheme and geotechnical engineering measures for mitigating the hazards to landfills in earthquake-prone areas are proposed.
