Quelques propositions au sujet des fondations profondes
Some suggestions about deep foundations
Géoconseil 10, avenue Newton 92350 Le Plessis-Robinson, France.
Dans une première partie, l’analyse d’un essai de chargement axial de pieu permet de rappeler les données expérimentales fondamentales.
La seconde partie propose un modèle de comportement des fondations profondes. Ce modèle est appliqué au cas de l’essai et les résultats de calcul sont confrontés aux mesures.
La conclusion met en question l’interprétation habituelle des essais de chargement à la lueur des apports du calcul en déplacement.
Abstract
A pile test with the detail of the measured values is presented in the first part.
In the second part, a very simple model for the loading of deep foundations is proposed and is used to make a simulation of the pile test. The model uses only two parameters for each soil layer. However the model is able to describe with accuracy the axial loading of a deep foundation.
In the conclusion, the prevalent interpretation of the pile load tests is discussed, subsequently to the results of the computation.
