This thesis deals with hydromechanical couplings in soils and more particularly focusing on the capillary collapse phenomenon. Although thoroughly studied at macroscopic scale in fine soils, the mechanisms governing capillary collapse in granular soils have been less observed.At first, the results concern the capacity to reproduce and to observe the phenomenon of capillary collapse at the scale of the specimen, called also the macroscopic scale.Thus, one of the first important objectives of this project concerned the preparation method of the specimens, which have to be loose enough to observe this phenomenon. The collapse potential, determined here by the one-dimensional collapse test, decreases with the mechanical stress. Moreover, when t...
