The fabric of undisturbed sand samples, six from a location known to have liquefied and five from a location that did not, from a site in Niigata, Japan, has been studied using petrographic thin sections and water content-soil water suction measurements. All samples were frozen after sampling but prior to transportation from the site to the laboratory. The gradational and particle shape characteristics of the medium to fine sands from the two locations are similar, but the void ratios of samples from the location known not to have liquefied were generally somewhat higher than for samples from the site that liquefied. Particle arrangements in the horizontal plane were slightly more random for the samples from the location that did not liquefy. These samples also exhibited a stronger degree of particle long axis orientation in vertical planes, a finding consistent to their higher resistance to liquefaction in cyclic triaxial tests. Significant differences in orientations of normals to interparticle contacts were not detected for samples from the two locations. The results of the suction-water content determinations indicated that samples from the location where the sand liquefied had a greater volume of small size pores than did the samples of sand that did not liquefy. As the samples were not frozen until after sampling, any disturbance that may have occurred during sampling is unknown. The results do suggest, however, that fabric in-situ is related to susceptibility to liquefaction. /Authors/
