Abstract

Rheology has a significant impact on the long-term consolidation behaviors of clays. The rheological consolidation theory plays a vital role in the prediction of deformation of the clays. In this study, the fractional derivative-based Kelvin model (FKM) and the fractional derivative-based Merchant model (FMM) are used to simulate the rheological characteristics of clays, and the continuous drainage boundary condition is adopted to consider the temporal continuity of the pore-water pressure at the boundary. Based on this, a one-dimensional consolidation model for the clays subjected to a time-dependent load is established, and then the semi-analytical solutions of the excess pore-water pressure (EPP), the settlement and the degree of consolidation are derived. Two sets of rheological parameters are back-calculated using the nonlinear fitting methods. The influences of the fractional order, viscosity coefficient and interface parameter on the rheological consolidation behaviors are investigated in depth through systematic parametric studies.
