Abstract
The lack of well documented case histories of landfill performance during earthquakes has made it difficult to calibrate our analytical tools and understanding of the earthquake resistance of these engineered structures. Moreover, it has not been possible to use case histories of landfill performance during earthquakes to demonstrate regulatory compliance. The 1994 Northridge earthquake provides an excellent opportunity to document the seismic performance of solid waste fills. In this paper, seven case records of landfill performance during the Northridge Earthquake are described. Back-analyses of the performance of four unlined and three geosynthetic-lined waste units are used to characterize the dynamic strength of the waste fill materials and geosynthetic liner interfaces. The results of these analyses indicate that the dynamic strength of waste fill is higher than the shear strength commonly assumed in static stability analyses and that the dynamic strengths of liner interfaces are generally consistent with values commonly used in practice.
