Model for large strain consolidation under constant rate of strain
International Journal for Numerical and Analytical Methods in Geomechanics, 2012SUMMARYA numerical model, called CCRS1, is presented for one‐dimensional large strain consolidation under constant rate of strain loading conditions. The algorithm accounts for vertical strain, general constitutive relationships, relative velocity of fluid and solid phases, changing compressibility and hydraulic conductivity during consolidation, and ...

Small-Strain and Large-Strain Modulus Measurements with a Consolidation Device
Journal of Testing and Evaluation, 2018Abstract By using a back-pressure saturated, constant rate-of-strain consolidation device with bender elements (BP-CRS-BE), values of large-strain constrained modulus (M) and small-strain shear modulus (Gmax) were obtained from tests performed on kaolinite soil specimens. The methodology and procedures that were utilized to obtain values

Recent Patents on Engineering, 2022
Abstract:: According to the universal one-dimensional consolidation equation introduced by Gibson, the governing equation with the excess pore water pressure as the control variable is derived, and the Fourier series solution under the boundary condition of single-sided drainage is deduced in detail by the standard mathematical physical method.

Enhanced CS2 Model for Large Strain Consolidation
International Journal of Geomechanics, 2012AbstractSince original publication in 1997, the CS2 numerical model has been widely used for consolidation analysis and has formed the basis for several more advanced consolidation models. In this paper, an enhanced version of the CS2 model is presented along with simulations to illustrate its new capabilities.

One-dimensional mathematical model for large-strain consolidation
Géotechnique, 1976A mathematical model is developed to represent the one-dimensional large-strain consolidation of a fully saturated clay. The fluid limit is postulated to be that water content associated with a ‘stress-free’ condition of the soil, and it is taken as the reference state from which strains are measured. Experimental results from a series of permeability

Model for large strain consolidation with compressible pore fluid
International Journal for Numerical and Analytical Methods in Geomechanics, 2004AbstractA numerical model, called CCPF1 (Consolidation with Compressible Pore Fluid 1), is presented for one‐dimensional large strain consolidation of a saturated porous medium with compressible pore fluid. The algorithm includes all the capabilities of a previous large strain consolidation code, CS2, written for incompressible pore fluid. In addition,

Piecewise-Linear Model for Large Strain Radial Consolidation
Journal of Geotechnical and Geoenvironmental Engineering, 2003A piecewise-linear model for radial consolidation, called RCS1, is presented. RCS1 accounts for vertical strain, soil self-weight, hydraulic conductivity anisotropy, radial and vertical flows, soil...

A case history of large strain consolidation
2003The embankment on the island Pag was built on a very soft clayey seabed in 1978. During the construction and after its completion, the embankment underwent extensive settlement. The paper presents the results of recently performed field and laboratory studies to analyse the monitored settlements and to predict future consolidation process.

The consolidation of a soil stratum, including self‐weight effects and large strains
International Journal for Numerical and Analytical Methods in Geomechanics, 1981AbstractA layer of fill deposited in a soft wet condition will consolidate under its own weight and will commonly undergo comparatively large strains in the process. Neither of these aspects of behaviour can be modelled by traditional consolidation theories.
