摘要：
Callovo-Oxfordian (Cox) argillite was investigated in the context of feasibility studies for an underground repository for nuclear waste. In this study, the influence of mineralogical composition and water content on the mechanical properties of the Cox argillite was investigated. The samples were drilled from three representative depths at which the rock formations have different mineralogical compositions. Micro-indentation and mini-compression tests were performed on samples with different water contents. The elastic and failure properties of argillite were determined and were found to be related to the mineralogical composition and water content. Both the elastic modulus and strength decrease with increasing clay and water contents.
