Abstract: The equations of the theories in previous paper are deduced for rock under triaxial compression.An example of presented models is gived. The example shows that the constitutive model can reflect the mechanical properties caused by the frictional sliding, mode-Ⅱ self-similar growth and kinking of closed microcracks under compression and swelling distortion caused by shearing. The opening of partial microcrack during kinking makes seepage increasing.

Key words: rock mechanics, rock, model, anisotropy, damage, seepage
