With the objective of an application to civil engineering, the improved expression of the disjoining pressure at the nanoscale is included in a modified form of Terzaghi’s effective stress principle for unsaturated expansive clays recently developed by our group in order to numerically simulate the hydro-mechanical behavior of expansive clays during water uptake. Data correspond to usage on the plateform after Editions universitaires europeennes October 19, Language: The evolution of the clay structure during shrinkage and swelling is followed with the aim of understanding the mechanism of swelling.

Citation Van Duy Tran. The polar nature of the water solvent is then implicitly taken into account through a Lennard-Jones potential averaging the different types of Van der Waals interactions. Water is no longer considered as a continuous solvent but as a fluid of individual polar molecules in order to recover existing experimental and modeling results such as the presence of discrete water layers in the interplatelet space gonnflantes the variation of the disjoining pressure with the interplatelet distance at low hydration level.

The clayey material hard and brittle when dry, presents the particularity of changing its consistence as a function of its water content.

Once the character of the swelling sensed in preliminary recognition phase, an estimate of the amplitude and the pressure of swelling can be established by correlations that tend to link the swelling parameters with geotechnical parameters obtained from identification tests.
These results are compared with those obtained for the oedometric swelling tests. Tuesday, December 12, – There’s a problem loading this menu right argiels. Different physical phenomena of increasing complexity are successively considered.

This behavior is essentially linked to some of environmental parameters of these soils, for example: Impact de la saturation cationique sur l’agencement microscopiques des argiles gonflantes et Depending on the particular structure of clay minerals, these modifications of consistence may be accompanied by more or less substantial volume variations, manifested, either, as a sharp increase of volume argoles phenomenon when the water content increases or shrinkage shrinkage phenomenon in period of marked rainfall.
