Identification des paramètres de comportement des sols injectés par analyse inverse d'essais pressiométriques
The improvement of the mechanical properties of a soil by injection of a new generation grout can be assessed either by laboratory tests or by field tests. It has been deduced from laboratory tests that a linear elastic—perfectly plastic model with a non associated Mohr-Coulomb failure criterion enables to roughly reproduce the mechanical behaviour of grouted sands. We propose in this paper to identify the parameters of this model by inverse analysis of pressuremeter tests. The procedure is based on the analytical expression of the pressuremeter curve given by (Yu and Houlsby, 1991) and a Newton-Gauss optimization algorithm. The results are then compared with the values of the parameters determined in the laboratory.
