This thesis is devoted to the study of the creep behavior of clay materials, based on two complementary approaches: an experimental process and a numerical modeling approach.In a first step, the creep behavior of two materials was studied experimentally, by performing a series of high pressure oedometric tests. These tests have demonstrated the hydric and thermal effect on the creep phenomenon of two materials. In a second step, a modeling was proposed taking into account the influence of microstructure, temperature and unsaturation on the macroscopic behavior of the material using a numerical homogenization approach. The representation of the microstructure was based on the definition of a representative volume elementary for periodic medi...
