One-dimensional consolidation problems

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1979
In analyzing real problems using the classical theory of one-dimensional consolidation it is necessary to make a number of simplifying assumptions, the effects of which cannot be determined easily. The nature of these errors is studied by comparing classical analyses with finite difference analyses that take into account time-dependent loading, large ...

One‐Dimensional Lagrangian Consolidation

Journal of Geotechnical Engineering, 1989
In the case of a mixed Spatial and Material description of Large-Deformation Consolidation, it is shown that if the geometry is updated through an expression for the velocity of solids, then the complete Lagrangian description is obtained.

Uncertainty of One‐Dimensional Consolidation Analysis

Journal of Geotechnical Engineering, 1985
The measured coefficient of consolidation, cυ, can have a substantial degree of variation even in a uniform clay layer. This paper, through a probabilistic analysis, examines the variability of one‐dimensional consolidation solutions. Both the single layer and the multilayer models are evaluated.

One-dimensional compression and consolidation of shales

International Journal of Rock Mechanics and Mining Sciences, 2016
Abstract This paper presents a comprehensive methodology for analysing the compression and consolidation behaviour of shales. An apparatus was designed to perform oedometric high-pressure tests by applying a maximum vertical total stress of 100 MPa and simultaneously controlling the pore water pressure of the specimen.

Probabilistic One-Dimensional Consolidation

Journal of the Geotechnical Engineering Division, 1977
The probabilistic analysis of one-dimensional consolidation requires as input the multivariate probability density function relating hydraulic conductivity, compressibility, and porosity. A Monte Carlo approach can be used to obtain solutions to hypothetical consolidation problems in which the soil properties are generated stochastically.

One-Dimensional Consolidation of Layered Systems

Journal of the Soil Mechanics and Foundations Division, 1970
An analytical solution to the layered consolidation problem for a general set of boundary conditions and an arbitrary load history is presented herein. An example is provided in which the soil profile consists of four compressible layers.

Strength of One Dimensionally Consolidated Clays

Journal of the Geotechnical Engineering Division, 1975
Ten series of undrained tests, each involving 13 tests with 13 stress paths and seven inclinations of the principal stresses, were conducted on four different one dimensionally consolidated clays. The results lead to the conclusions that there does not exist a unique relationship between water content and effective stress during shear, and that the ...

Numerical approximation of one‐dimensional consolidation

International Journal for Numerical Methods in Engineering, 1972
AbstractA generalized finite difference scheme is developed to represent the one‐dimensional consolidation process. The difference equations are derived from integral balance equations which represent the soil as a mixture of two constituents. No restrictions are placed on the soil constitutive properties or stratigraphy.

One-dimensional Consolidation of Thawing Soils

Canadian Geotechnical Journal, 1971
The physics of consolidation of a thawing soil is formulated in terms of the well-known theories of heat conduction and of linear consolidation of a compressible soil. A moving boundary problem results, and closed form solutions have been obtained for several cases of practical interest.

Rectangular hyperbola fitting method for one dimensional consolidation

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1981
Abstract The time factor—degree of consolidation relation from the Terzaghi theory is assumed as a rectangular hyperbola over a wide range of the time factor. A new method is developed for determination of the coefficient of consolidation Cv from laboratory consolidation test data.
