Abstract

Abstract

A semi-analytical 1D consolidation solution of saturated soft clay was derived via the Laplace transform by means of the spring pot-based fractional-order Kelvin model and in view of changing inner stresses along the depth of the soft clay. Firstly, the validity of the semi-analytical solution was verified through comparison with the referential results. Then, the effects of different fractional orders, total stress ratios and multi-grade linear loadings on the consolidation settlement and the pore water pressure of the saturated soft clay were analyzed based on the semi-analytical solution in detail. The work provides a theoretical basis for the related practical geotechnical engineering.
