This document discusses two methods for determining the coefficient of consolidation (Cv) of soil through consolidation testing: the square root of time fitting method and the logarithm of time fitting method. The square root of time fitting method involves plotting dial readings versus the square root of time to obtain Cv. The logarithm of time fitting method involves plotting dial readings versus the log of time and using the 50% consolidation point to calculate Cv based on drainage path and time.
