dc.descriptionAbstract: Relationships between sand fabric, sample preparation method, and liquefaction and drained compression behavior under triaxial loading were determined' for Monterey No. 0 sand. Reproducible samples were fabricated at 50 percent relative density using pluvial, moist tamping, and moist vibration methods of compaction. Pluviation and moist tamping were used to prepare samples at 80 percent relative density. Fabric was characterized by particle long axis and interparticle contact orientations. Samples at both 50 percent and 80 percent relative density prepared by dry pluviation exhibited much lower strength under cyclic loading than did samples prepared by the other methods. At 50 percent relative density samples prepared by pluviation were less stiff, compressed more prior to dilation and dilated less than samples prepared by the other methods. Differences were less pronounced at 80 percent relative density. Preferred orientation of long axes of particles developed in the horizontal direction for each of the methods studied, with the intensity increasing in the order moist vibration (nearly random), moist tamping, dry pluviation. At a relative density of 50 percent preferred orientation of interparticle contact planes existed in the range of ±0° to 30° of the horizontal with the proportion increasing in the order dry pluviation, moist tamping, moist vibration. At 80 percent relative density more interparticle contact plane orientations were in the range of ±0° to 30° of the horizontal for samples prepared by dry pluviation than by moist tamping. For a given average relative density substantial variations in density in a longitudinal direction could be seen in X-radiographs. These variations differed for sample preparation by different methods. NOTE: This file is large. Allow your browsers several minutes to download the file.-
