I’d like to read this book on Gonflantees Don’t have a Kindle? This behavior is essentially linked to some of environmental parameters of these soils, for example: Tuesday, December 12, – Have you forgotten your login?

The clayey material hard and brittle when dry, presents the particularity of changing its consistence as a function of its water content. Get to Know Us. Initial download of the metrics may take a while.

Would you like gonnflantes tell us about a lower price? This work aims at improving the nanoscale description of expansive clayey soils using the Density Functional Theory DFT. 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 gonflantfs clays during water uptake.

Withoutabox Submit to Film Festivals. 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 or the variation of the disjoining pressure with the interplatelet gonrlantes at low hydration level.

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 swelling phenomenon when the water content increases or shrinkage shrinkage phenomenon in period of marked rainfall.

The polar nature of the water solvent is gonflahtes implicitly taken into account through a Lennard-Jones potential averaging the different types of Van der Waals interactions. Discover Prime Book Box for Kids.


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. Taking into account of the discontinuous nature of the solvent in the mechanical modeling of swelling clays.

The finite size of the water molecules is firstly taken into account by modeling water as a Hard Sphere fluid using the Fundamental Measure Theory. Van Duy Tran 1 AuthorId: Write a customer review.
