RESUMEN: Se presentan los resultados de un estudio experimental para la evaluación de los efectos de sobre-consolidación en la licuefacción de suelos granulares. Los ensayes consistieron en pruebas de cortante en arenas con aristas suaves y con diferentes valores de porosidad, razón de sobre-consolidación, así como esfuerzos de confinamiento y cortante. Los resultados indican que la propensidad a la licuefacción se ve influenciada grandemente por la sobre-consolidación. Aun a niveles bajos de sobre-consolidación la resistencia a solicitaciones cíclicas puede aumentarse significativamente. El factor Kα también se vé influenciado por la razón de sobre-consolidación; sin embargo esta razón no afecta el factor de corrección Kσ. Una consideración adecuada de los beneficios de la sobre-consolidación puede resultar en ahorros económicos importantes en los diseños resistentes a la licuefacción.
