Summary:This experimental study was designed to assess the effects of soil water saturation on the liquefaction of Hostun RF sand. Cyclic undrained triaxial tests were conducted at different soil saturation levels, as given by Skempton's coefficient, and liquefaction potential curves constructed for each value of this coefficient. Our findings indicate that a lower soil saturation level results in the increased resistance of the sand to liquefaction, in agreement with the tendency observed in other sands. In addition, the variation in sand resistance to liquefaction produced with Skempton's coefficient was found to be consistent with the semi- empirical relation proposed by Yang et al. (2004). Keywords: sand, partial saturation, liquefaction, Skempton's Coefficient, triaxial Este estudio experimental fue disenado para comprobar los efectos de la saturacion de agua en suelos bajo la licuefaccion de arena RF Hostun. Tests ciclicos de tipo triaxial no drenado fueron elaborados a diferentes niveles de saturacion del suelo, como se obtiene por el coeficiente de Skempton, y se obtuvieron curvas de potencial de licuefaccion para cada uno de los valores de este coeficiente. Nuestros resultados indican que un nivel de saturacion bajo de suelo durante el incremento de la resistencia de la arena a la licuefaccion, estando de acuerdo con la tendencia observada en otras arenas. Por otro lado, se observo que la variacion de la resistencia de las arenas a la licuefaccion producida mediante el coeficiente de Skempton es consistente con la relacion semiempirica propuesta por Yang et al. (2004). Palabras clave: arena, saturacion parcial, licuefaccion, Coeficiente de Skempton, triaxial
