Viscosity and secondary consolidation in one-dimensional loading

Examination on Time-dependent Soil Models in One-dimensional Consolidation

This paper reviews the performance of two time-dependent constitutive models in predictions of one-dimensional consolidation. The Soft-Soil Creep model [1] is an example of an elastic-viscoplastic formulation that incorporates a timedependent state variable to estimate viscoplastic deformation. We show that the SSC model is equivalent to the isotache formulation proposed by Imai [2], as both ar...

a numerical approach for one dimensional thermal consolidation of clays

in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...

One Dimensional Non-linear Consolidation of Unsaturated Fine Grained Soils

In the content of this study, non-linear consolidation behavior of unsaturated soils was investigated. In this respect a non linear differential equation for consolidation has been proposed. This proposed differential equation and its solutions enlighten both the diffusive characteristics and the time rate of settlement of soils. Besides, this study also enables to perform the matric suction ca...

Title : One - Dimensional Modeling of Secondary Settling

Unit 7 Secondary Consolidation

One-dimensional consolidation of soils is conveniently divided into three portions, viz., (1) initial compression, (2) primary consolidation, and (3) secondary consolidation. Such a classification involves the clear implication that the three effects proceed in that order. Initial one-dimensional compression of saturated clays is negligible because of the low compressibility of the pore water. ...
