Effect of filtration coefficient determination method on the scale effect in water-saturated fine-grained soils

Rosine, TN; Toma-Sabbagh, TM

Abstract

The methods of calculating the filtration coefficient k from data obtained in tests performed
under the conditions of one-dimensional consolidation in terms of consolidation
coefficient cv , compressibility av and volume compressibility mv, average particle size D10, and void ratio e are investigated. The evaluated k used in the PLAXIS software system is taken for comparison. The filtration coefficients determined by different methods were
used to study the scale effect in the Mohr-Coulomb model. The excess pore pressure for different diameter to height ratios of a sample was in better agreement with the values
predicted by using k determined in PLAXIS. This is explained in part by the variability of the filtration coefficient during consolidation.
