A semi-empirical relationship for the small-strain shear modulus of soft clays

The small-strain shear modulus (G max ) is a soil property that has many practical applications. The authors compiled a database of G max measurements for 40 normally consolidated to slightly overconsolidated low to high plasticity clays. Using these data, the authors propose a semi-empirical relationship between G max , effective stress (σ'v or σ'c), preconsolidation stress (σ'p) and in-situ void ratio (e0) for four ranges of plasticity index...
