Coupling versus uncoupling in soil consolidation
International Journal for Numerical and Analytical Methods in Geomechanics, 1991AbstractCoupling and uncoupling between the equilibrium and mass balance equations in soil consolidation problems in investigated in detail. A procedure for judging the strength of coupling is indicated. In the applications, particular emphasis is given to subsidence problems where the coupled nature of the problem is still sometimes questioned.

Probabilistic Analysis of Coupled Soil Consolidation
Journal of Geotechnical and Geoenvironmental Engineering, 2010Coupled Biot consolidation theory was combined with the random finite-element method to investigate the consolidation behavior of soil deposits with spatially variable properties in one-dimensional (1D) and two-dimensional (2D) spaces. The coefficient of volume compressibility ( mv ) and the soil permeability (k) are assumed to be lognormally ...

Hippocampo-cortical coupling mediates memory consolidation during sleep
Nature Neuroscience, 2016Memory consolidation is thought to involve a hippocampo-cortical dialog during sleep to stabilize labile memory traces for long-term storage. However, direct evidence supporting this hypothesis is lacking. We dynamically manipulated the temporal coordination between the two structures during sleep following training on a spatial memory task ...

Coupled consolidation theory with non-Darcian flow
Computers and Geotechnics, 2002Abstract Some evidence shows that the flow of pore water in the soil may not obey Darcy's law that is a basic assumption in most of the existing consolidation theories. One of the nonlinear flow relationships, non-Darcian flow (described by the threshold gradient i l and exponent m ), was incorporated in the coupled consolidation theory in this ...

Coupled approach in simulation of soil consolidation
ce/papers, 2018AbstractThe aim of this paper is to present a mathematical framework and its corresponding coupled finite element discretization for fully saturated porous media. The model is developed as a coupled displacement‐pressure formulation in which the porous medium is composed of a soil skeleton and water in the pores. The considered problem in this paper is

Coupled consolidation analysis of pipe–soil interactions
Canadian Geotechnical Journal, 2013Current design practice for pipe–seabed interaction in soft soils is generally based on the assumption of undrained behaviour throughout laying and subsequent operation. In reality, drainage and consolidation around a partially embedded pipe can have a marked effect on the vertical penetration and horizontal breakout resistance. In this paper, a large-

Model for Coupled CRS Consolidation and Contaminant Transport
Geoenvironmental Engineering, 2014This paper describes the development of a numerical model, called CSTCRS1, for one-dimensional coupled contaminant transport and large strain consolidation under constant rate of strain (CRS) loading conditions. Numerical simulations using CSTCRS1 indicate that concentration boundary conditions can have an important effect on contaminant transport ...

Modeling of Consolidation Considering Coupled Soil-Fluid Interaction
2021Expulsion of excess pore water pressure caused by load applied for longer time which results in reduction of volume of the soil is termed as consolidation of soil mass. The response in terms of displacement is dependent of soil mass properties, applied loading, pore water pressure, and time.

Coupled Chemical Shrinkage and Consolidation: Some Benchmark Solutions
Transport in Porous Media, 2014Mixtures of cement and mine waste are used as backfill in underground mines to provide support, which enables increased mineral extraction. Unlike most cemented material, the properties of mine backfill are relied upon immediately after cement is added and the material deposited underground.
