Effect of Consolidation Ratios on Maximum Dynamic Shear Modulus of Sands

The dynamic shear modulus (DSM) is the most basic soil parameter considered in earthquake or other dynamic loading conditions. The DSM can be obtained through testing in the field or in the laboratory. This article reports on a study that used resonant column tests to determine the effect of consolidation ratios on the maximum DSM for two types of sand. The authors also present an increment formula to obtain the maximum DSM for cases of consolidation ratio kc>1. The results indicate that the maximum DSM rises rapidly when kc is near 1 and then slows down, which means that the power function of the consolidation ratio increment kc-1 can be used to describe the variation of the maximum DSM due to kc>1. The results also indicate that the increase in the maximum DSM due to kc>1 is significantly larger than that predicted by Hardin and Black’s formula. The authors conclude that the consolidation ratio is an important factor in the differences between the field and laboratory determinations of the maximum DSM of soils.
