TIME- AND STRESS-COMPRESSIBILITY INTERRELATIONSHIP

For any natural soil a unique relationship exists between secondary compression index C sub a and compression index C sub c. It is postulated that the relation between time compressibility and effective stress compressibility holds true at any time effective stress, and void ratio during consolidation. The observed values of C sub a/C sub c for a variety of natural soils, including highly sensitive clays, organic silts, and peats, are in the range of 0.025 to 0.10. The shape of the settlement curve in the secondary range can be predicted from the shape of the void ratio-logarithm of effective stress curve and the relationship between C sub a and C sub c. The predicted results are completely consistent with laboratory observations and with the existing field case records. The magnitude of C sub a/C sub c can be used to predict the shape of the volume change-logarithm of time curve in the transition from primary to secondary. The procedure provides a quantitative explanation for the observed shapes of the settlement curve. /Author/
