Nonlinear Consolidation Analysis of Soil-Cement Pile

Applied Mechanics and Materials, 2011
A few consolidation solutions of soil-cement pile have been derived by the assumption that the coefficient of volume compressibility and coefficient of permeability of soil and pile is constant. However, the value of coefficient of volume compressibility and coefficient of permeability of soil and pile varies along depth during the consolidation ...

Small-Strain Nonlinearity of Normally Consolidated Clay

Journal of Geotechnical and Geoenvironmental Engineering, 2007
This paper addresses the small-strain undrained shear behavior of clays based on an extensive testing program conducted on normally consolidated resedimented Boston blue clay (RBBC). The uniformity and reproducibility in the behavior of this soil permit a detailed study of the role of consolidation stress level, preshear consolidation stress path ...

Oedometer Consolidation Test Analysis by Nonlinear Regression

Geotechnical Testing Journal, 2008
Abstract A numerical method based on least squares nonlinear regression for the evaluation of the consolidation parameters of soils from consolidation tests is presented. A model which includes the initial compression, the primary consolidation, and the secondary compression is used in the regression.

Implicit-explicit schemes for nonlinear consolidation

Computer Methods in Applied Mechanics and Engineering, 1983
Abstract A general analytical procedure capable of performing linear and nonlinear consolidation analysis of saturated porous media is proposed. A brief review of the coupled field equations is included and the constitutive assumptions are stated explicitly.

Nonlinear and elasto-plasticity consolidation models of unsaturated soil and applications

Applied Mathematics and Mechanics, 2001
The non-linear constitutive model suggested by the authors and the Alonso's elasto-plasticity model of unsaturated soil modified by the authors are introduced into the consolidation theory of unsaturated soil proposed by CHEN Zheng-han, and the non-linear and the elasto-plasticity consolidation models of unsaturated soil are obtained.

Solution of some nonlinear one‐dimensional consolidation problems

Communications in Applied Numerical Methods, 1987
AbstractThe analysis of nonlinear one‐dimensional consolidation of clay is considered. An algorithm is presented which allows nonlinear clay parameters to be accommodated in the prediction of both the magnitude and the rate of consolidation. The method is based on the finite element solution of Biot's coupled consolidation problem, together with a ...

Nonlinear consolidation in randomly heterogeneous highly compressible aquitards

Hydrogeology Journal, 2017
Severe land subsidence due to groundwater extraction may occur in multiaquifer systems where highly compressible aquitards are present. The highly compressible nature of the aquitards leads to nonlinear consolidation where the groundwater flow parameters are stress-dependent. The case is further complicated by the heterogeneity of the hydrogeologic and

Variation of hydraulic gradient in nonlinear finite strain consolidation

Journal of Central South University, 2014
In the research field of ground water, hydraulic gradient is studied for decades. In the consolidation field, hydraulic gradient is yet to be investigated as an important hydraulic variable. So, the variation of hydraulic gradient in nonlinear finite strain consolidation was focused on in this work. Based on lab tests, the nonlinear compressibility and

Consolidation of a nonlinear poroelastic layer in finite deformations

1996
Summary: The effects of nonlinear material behaviour and finite deformation in the analysis of the consolidation of a layer of a porous medium subjected to a step load are addressed within the framework of nonlinear poroelasticity. The validity of Terzaghi's effective stress concept is confirmed for a nonlinear material behaviour under finite ...
