- Abstract
- Research was undertaken to investigate the effects of grain-size distribution gradation on dynamic properties and on liquefaction potential of granular soils. Resonant column tests were performed to determine the dynamic shear moduli and damping ratios of granular soil samples prepared from a Denver sand. Cyclic triaxial test cells and an MTS closed-loop servo control material testing machine were used to determine liquefaction potential. Results indicate that the shear modulus of soils at small strains is strongly dependent on the uniformity coefficient. The liquefaction potential was found to be strongly affected by the mean diameter.
