δ-t/δ Method for the Determination of Coefficient of Consolidation
Terzaghi's theoretical time factor, degree of consolidation relationship when plotted as U versus T/U, enables one to get a convenient form of curve-fitting method to determine the coefficient of consolidation. The time corresponding to 90% consolidation can be obtained more precisely from the proposed δ-t/δ method than the δ−√t method. The present article deals with the theoretical and practical aspects of results obtained from δ-√tand δ-t/δ representations.
