A PARAMETRIC ANALYSIS FOR THE DAFALIAS-KALIAKIN BOUNDING SURFACE VISCOPLASTIC MODEL-BASED ON THE DIFLUPRESS LD TEST

[en] In order to predict delayed settlements of heavy structures, the authors decided to use the elasto-viscoplastic model of Dafalias-Kaliakin. To identify the parameters of the constitutive equations, they use above all the data of a new in-situ test, the Diflupress L.D. designed to approach the creep behavior of soil. In a first section, the principle of the model is presented. Then, the important parameters of the model are identified, mostly from in-situ test data since the laboratory tests data are not numerous and reliable. Finally, a study of sensitivity on the parameters which influence the viscoplastic response of the model is made.
