摘要：Callovo-Oxfordien (COx) claystone, as a potential host rock for nuclear waste disposal, is investigated for its oedometric compression and swelling behaviour in this paper. Based on results of high pressure oedometric compression experiments, a model is proposed to explain the swelling behaviour of COx claystone under different stress. A method using the variation of porosity is also proposed to determine the damage of rock quantitatively. Mercury Intrusion Porosimetry (MIP) and Scanning Electron Microscopy (SEM) were applied in order to get a clear map of the swelling process in micro scale.
