Consolidation analysis by the extended Taylor method (ETM)‎

الملخص EN

The Taylor √t method is extended for improving the estimation of the end-of-primary (EOP) settlement δp and coefficient of vertical consolidation cv.

The extended Taylor method (ETM) utilizes the same graphical procedure of the conventional Taylor method, but this procedure is repeated twice at any two U values greater than 52.6 % instead of the one used in the Taylor method at 90 % ; U is the average degree of consolidation.

The ETM explicitly relates cv to the slope of the initial linear portion of the δt - √t curve as well as the EOP settlement δp ; δt is the settlement at time t during consolidation.

The ETM can be applied with a minimum of four consolidation data points for estimating δp and cv.

Two types of EOP settlements are distinguished ; firstly, local EOP settlement δpi obtained by matching experimental results to theory at a particular U value ; secondly, global EOP settlement δp obtained by extrapolation using two or more local EOP settlements.

The ETM explains the observed differences in cv values estimated by the existing methods in terms of the differences in δp values obtained by these existing methods.

Experimentalresults are used to validate and compare the extended Taylor method with the existing methods.
