Influence of Grain Size Distribution on the Undrained Dynamic Properties of Saturated Sand
The majority of previous research on dynamic properties (dynamic shear modulus and damping ratio) of clean sand involved either dry sands or saturated sands subjected to drained cyclic loading tests or undrained tests which allowed for excess pore pressure dissipation between each cycle of loading. The majority of the research determined dynamic properties at small shear strain amplitudes. Further, the influence of grain size distribution was not systematically studied. In this paper, dynamic properties were evaluated from each hysteresis loop produced by an undrained cyclic triaxial test. The analysis of statistical correlation was performed to determine the strength of correlation between the dynamic properties and factors such as the influence of the number of loading cycles, the shear strain amplitude, and the grain size distribution characteristics. A functional relationship was developed between the dynamic shear modulus and shear strain.
