Analysis Of Time-Deflection Consolidation Data, E. Gregory Mcnulty
Analysis Of Time-Deflection Consolidation Data, E. Gregory Mcnulty
Kentucky Transportation Center Research Report
A computerized statistical curve-fitting algorithm has been developed for determining the time-dependent properties of conventional (load-incremental) consolidation test data. Analytical models of the graphical methods developed by Taylor and Casagrande and of the Naylor-Doran method of successive approximations determtne values for the coefficients of consolidation, permeability, and the values of deflection corresponding to the begimltng and endtng of primary consolidation. The coefficients of volume change and secondary compression are also calculated. A modified statistical definition is used to select the linear portions of the data curves and is applicable to other data-fitting problems. After the Naylor-Doran method has been used, …
