Abstract
The time factor, T, and the degree of consolidation, U, from Terzaghi's theory of consolidation can be shown to have a straight line relationship when plotted as log[– T/log (T/U)] versus log T. Oedometer tests were conducted on five soils with a wide variation in properties. The results obtained establish straight line variation between log[t/log(7/δ)] and log t plots. Using this property, a method is proposed to predict the compression (δ) versus time (t) behaviour of clayey soils by measuring the compression values of a soil specimen at only two time intervals in oedometer test. Variation of δ with t is predicted using the proposed method for some of the soils tested, and the computed values of Cvare compared with the actual experimental Cvvalues. Some of the published test results are used to validate the proposed method. Key words : coefficient of consolidation, clays, oedometer test, time–compression, settlements.
