Modélisation du processus de sédimentation-consolidation des vases estuariennes: approche continue unidimensionnelle
TLDR
In this article, the authors propose a modele continué du processus de sedimentation-consolidation base sur les equations de conservation de deux phases compressible, which permits d'envisager la prise en compte de phenomenes negliges jusqu'alors: fluage, floculation, ecoulements non-darciens, etc.Abstract:
L'etude de la sedimentation et de la consolidation des sediments cohesifs presente un grand interet scientifique par son aspect interdisciplinaire, a la frontiere hydraulique-geotechnique et en raison de l'importance de ses applications a la gestion des zones cotieres. Nous proposons d'associer les points de vue hydraulique et geotechnique en vue d'etablir un modele continu du processus de sedimentation-consolidation base sur les equations de conservation de deux phases compressibles. Ce modele, general et evolutif, permet d'envisager la prise en compte de phenomenes negliges jusqu'alors: fluage, floculation, ecoulements non-darciens, ... Il constitue donc un element fondamental pour une modelisation globale et precise de la dynamique sedimentaire en estuaire.read more

Experimental study of cement grout: Rheological behavior and sedimentation
TL;DR: In this article, the authors used a gammadensitometer bench to measure the degree of hydration of fresh rheologically fresh cement paste with W/C ratios (water/cement ratio) varying between 0.35 and 1.
Interprétation et modélisation numérique d'essais oedométriques et de perméabilité à niveau variable réalisés sur des argiles Champlain
TL;DR: In this paper, the authors used a variable-head permeability test conducted between the loading steps of oedometer tests to evaluate the conductivite hydraulique in fine-grained soils.

The theory of one-dimensional consolidation of saturated clays. II. Finite nonlinear consolidation of thick homogeneous layers
TL;DR: In this paper, the one-dimensional consolidation of a thick clay layer, initially consolidated fully under its own weight, is considered and account is taken of the variation of the coefficients of permeability and...

A note on sedimentation and consolidation
V. Pane,Robert L. Schiffman +1 more
TL;DR: In this article, an extended equation is derived which governs the sedimentation and simultaneous consolidation of pelagic sediments, and an example of the implementation of this theory is also given in this note.
