Abstract

In areas of high seismicity, seismic stability often controls hazardous and solid waste landfill closure design. The undrained shear strength (Su) of the waste mass is fundamental to seismic slope stability analyses. The value of Su for hazardous waste fill is often difficult to characterize. The physical and chemical natures of the waste fill typically preclude laboratory testing of the materials. In certain cases, Cone Penetration Test (CPT) soundings can provide a viable technique for evaluation of Su provided that the cone shear strength factor Nk can be established. If hazardous waste materials laboratory testing is not an option, Nk may be evaluated based upon results of non-intrusive in situ testing. This paper presents a case history of the seismic stability assessment of a hazardous waste site in which Nk was established from the results of non-intrusive Spectral Analysis of Surface Waves (SASW) soundings and empirical correlations to shear strength of soils. Generalization of the proposed methodology to other sites should be done with caution owing to variability among the parameters used in the analyses.
