By using the resonant column tests, the effect of the consolidation ratios on the maximum DSM of the soil is investigated and an incremental formula for calculating the maximum DSM for the cases of the anisotropic consolidation is presented. The silty clay, silt and sludgy soil of China are employed in the tests to establish the basic formula in the paper. The form of the formula is a power function to describe the relation between the ratio of the maximum DSM’s due to anisotropic and isotropic consolidations and the increment of consolidation ratio, Gmax/G0=1+C·(kc-1)B. The new formula indicates that the maximum DSM is the power of kc-1 instead of the nearly linear relation in Hardin and Black’s and the increasing degree of the maximum DSM due to kc>1.0 is significantly larger than that described by Hardin and Black’s formula. Compared with sand, the increment of the maximum DSM for silty clay due to anisotropic consolidation is much larger than that of sand.
