The Callovo-Oxfordian (COx) claystone has been selected as a potential host rock for underground radioactive waste repository in France. The present thesis is devoted to experimental investigation of the poro-mechanical behavior of COx claystone. The emphasis is put on the study of influences of structural anisotropy and loading path. Both instantaneous and time dependent behaviors are considered. For this purpose, a series of laboratory investigations including axial extension creep tests with different loading orientations, shear creep tests on fractured samples with gas permeability evolution measurement, tests for determination of Biot’s and Skempton’s coefficients, lateral decompression and axial extension tests with poroplastic cycles...
