Wetting in granular materials induces changes in the morphology of capillary bridges which pass from an isolated form (between two neighboring grains) to a merged form (between several neighboring grains). These changes in the morphology of the liquid bridges impact the mechanical behavior of these materials, and can lead to instabilities such as capillary collapse. The thesis presents a multi-scale experimental approach in the laboratory of the capillary collapse of granular materials during wetting. The approach concerns the three scales: macroscopic of a Representative Elementary Volume, mesoscopic of several grains and local of three or four grains. At the macroscopic scale, the wetting tests, carried out in a triaxial cell, allowed the...
