Influence du retrait et de la variabilité naturelle des sols argileux sur le comportement des fondations de maisons individuelles

Abstract: Les maisons individuelles sont particulièrement sensibles aux tassem ents différentiels provoqués par les phénom ènes de retrait-gonflement des sols argileux. La reconnaissance sur les sites de construction de la présence de sols argileux est donc primordiale. La méthode VLF-R (Very Low Frequency) en mode résistivité (R), testée sur un site de 25 000 m2, s'avère être un outil performant pour atteindre cet objectif mais égalem ent pour mettre en évidence la variabilité lithologique des sols sur un site.

“…The reaction of the soil and the stresses, such as the bending moment and the shear forces on its two sides, are also represented. The soil reaction coefficient k [kPa] is influenced by several factors, such as the load applied, the foundation's geometry, and its stiffness (Denis et al, 2007) . This coefficient increases when the foundation is flexible, and the soil is rigid.…”
