Abstract

From the Terzaghi's theory of consolidation, it can be shown that the T/U versus T relation is a rectangular hyperbola over a fairly wide range of degree of consolidation. In the plot of T/U versus T, a straight line is fitted for the range of 60 to 90% degree of consolidation with a high precision. A method of calculating the coefficient of consolidation Cv is presented. The results are compared with the results obtained by the conventional methods, viz, square root of time fitting method and logarithm of time fitting method.
