Identification des paramètres mécaniques des sols par analyse inverse sur des ouvrages de soutènement

Levasseur, Séverine

This paper is dedicated to the parameter identification of the Mohr-Coulomb constitutive model from horizontal displacements of a sheet pile wall. An optimization method based on a genetic algorithm is proposed. This robust optimization method localizes quickly a set of solutions around the optimum value. Then, the set identified is described by a principal component analysis. This new inverse analysis method based on a genetic algorithm and a principle component analysis permits to define an ellipsoid set of solutions which is characteristic of the soil properties for geotechnical studies.
