The slope method explicitly relates the coefficient of consolidation cv to the slope of the initial linear segment of the observed δt- curve and to the end of primary settlement δp. The slope method utilizes the same graphical construction as the Taylor method but eliminates the use of the factor 1.15 that usually leads to lower δp and higher cv as compared to the Casagrande method and pore water pressure measurements. Instead, the point at which the δt- curve deviates from the linear portion (at U of about 50 %) is considered for estimating δp. Oedometer test results on four soils show that the cv values of the slope and Casagrande methods are comparable but lower than those of the Taylor method.
