CONSOLIDATION OF THIN CLAY LAMINA USING LAURENT TRANSFORM

Abstract

This work evaluates the rate of consolidation by Laurent series using transformations. A clear comparison is made between Fourier and Laurent outputs for variation of degree of consolidation with time factor experimentally and verified theoretically. Laurent series has been observed to be consistent for explaining consolidation of clay layer with low thickness. As the Laurent series is a type of convergent series therefore all the variation in sample thickness & pore water pressure converges to a single value. Curve obtained by Laurent series continuous in nature. With the help of Laurent series process of consolidation can be studied even at microscopic level and for all kind of soils. This analysis can be well supported & explained by conversion of nature of plots from Fourier transformation to Laurent transformation.
