Liquefaction potential of pond ash obtained from the ash pond located at Panki Thermal Power Station, Kanpur, India is evaluated by laboratory static triaxial tests and standard penetration tests (SPT) up to a depth of 20 m. Residual strength approach by Norris et al. (1997) has been used to study the residual state characteristics of remolded ash samples. Consolidated rebounded drained triaxial tests with volume change measurements are performed on the remolded ash samples with three relative densities of 30%, 50% and 75%. The results obtained are compared with the stress-controlled consolidated undrained triaxial test, the method reported by Poulos et al. (1985). It is observed that the liquefaction behaviour can be predicted for 30% relative density within the strain levels. The steady state line obtained from laboratory experiments is compared with the model reported by Cubrinovski and Ishihara (2000). The liquefaction potential based on penetration data is evaluated by the model proposed by Seed et al. (1983). J. Ross Publishing, Inc. © 2010
