ABSTRACT
Numerical modelling of long-term behaviour of embankments on soft soils can require a significant amount of laboratory tests in order to derive all the necessary input parameters. Laboratory test results are strongly dependent on sample quality. Consequently, the quality of a finite element analysis is also dependent on the quality of the retrieved samples. The intent of this paper is then to evaluate the applicability of CPTu test results to determine preconsolidation stress for settlement calculations in soft soils when limited number of laboratory tests is available. The anisotropic Creep-SCLAY1S model is used for this purpose. The Creep-SCLAY1S model can capture the anisotropic visco-plastic behaviour and loss of soil structure after yielding. Settlement records from Murro test embankment are exploited to evaluate the practical implications of the proposed procedure.
