The elastic coefficients of the theory of consolidation

Journal of Applied Mechanics, 1957
Abstract The theory of the deformation of a porous elastic solid containing a compressible fluid has been established by Biot. In this paper, methods of measurement are described for the determination of the elastic coefficients of the theory.

Analysis and Estimation of the Coefficient of Consolidation

Geotechnical Testing Journal, 1995
Abstract Consolidation is one of the most important behaviors of saturated fine-grained soils that needs to be understood for settlement analysis of these soils. The two most important aspects of laboratory consolidation tests are: (1) estimation of the compression index (Cc), used to predict total settlement of normally consolidated ...

Modified Terzaghi consolidation curves with effective stress-dependent coefficient of consolidation

Géotechnique Letters, 2012
One of the assumptions of the standard consolidation theory used in soil mechanics is that the coefficient of consolidation is a material property that remains constant during the consolidation process. This note demonstrates numerically the effect on the consolidation rate of a coefficient of consolidation that changes with increasing effective stress.

In situ estimation of the coefficient of consolidation in clays

Canadian Geotechnical Journal, 1990
An investigation was conducted to demonstrate the applicability of cylindrical piezocone and flat piezoblade tests for providing reliable estimates of the coefficient of consolidation in clays. Coefficients of consolidation were calculated from piezocone dissipation tests for different degrees of consolidation using theoretical time factors to provide

Consolidation Coefficient Calculation Based on Consolidation Rate Attenuation Method

Applied Mechanics and Materials, 2012
This paper proposes a new partial-analytical consolidation coefficient calculation method as consolidation rate attenuation method based on the 1st-order series solution to one-dimensional Terzaghi theory. According to the consolidation rate attenuation curves, consolidation coefficient can be obtained by the linear attenuation part fitting.

Assessment of the coefficient of consolidation with Queensland data

Australian Geomechanics Journal, 2023
Established relationships between the coefficient of consolidation (cv) and index tests are used during both preliminary design and as a cross check during detailed design. The laboratory oedometer test provides compressibility parameters and a lower bound of cv, while the coefficients of consolidation are preferred from the field dissipation tests ...

Coefficient of Consolidation by the Slope Method

Geotechnical Testing Journal, 2008
Abstract The slope method explicitly relates the coefficient of consolidation cv to the slope of the initial linear segment of the observed δt-t curve and to the end of primary settlement δp. The slope method utilizes the same graphical construction as the Taylor method but eliminates the use of the factor 1.15 that usually leads to ...

Coefficient of consolidation from piezocone measurements

Géotechnique, 2005
Pore pressure dissipation tests were carried out employing two miniature piezocones, with areas of 1 cm2 and 5 cm2, in a bed of reconstituted kaolin. By using independently determined values of the coefficient of consolidation, the results were interpreted to derive appropriate values of rigidity index for use with the theory of Teh & Houlsby.

Coefficient of Consolidation by Inflection Point Method

Journal of Geotechnical and Geoenvironmental Engineering, 1999
The coefficient of consolidation in the Terzaghi theory of consolidation has been commonly determined by fitting the theory to observed compression with time in an incremental loading oedometer test. The Terzaghi theory is applicable to compression and swelling. A similar coefficient governed by horizontal permeability is used in the Barron formulation

Coefficient of consolidation by end of arc method

Journal of Central South University, 2015
One of the most important issues in geotechnical engineering is excess pore pressure caused by clay soil loading and consolidation. Regarding uncertainties and complexities, this issue has long been the subject of attention of many researchers. In this work, a one-dimensional consolidation apparatus was equipped in a way that pore water pressure and ...
