Abstract: The micromechanics is used to establishing a constitutive model and a seepage model of seeping rock in compression. The process of swelling distortion caused by shearing and seeping are considered for the equations during establishing the constitutive models. An anisotropic seepage model, thingking about microcrack extending, distortion and hydraulic pressure, is established. The frictional sliding, mode-Ⅱself-similar growth and kinking of closed microcracks under compression and their influences on the mechanical properties of rock are studied in detail.

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