中文摘要：
采用细观力学研究了岩石损伤变形过程和渗流过程.在本构模型中增加了对剪胀变形机理和渗流对变形影响的内容,同时按照微裂纹发展过程建立了考虑微裂纹扩展、变形和渗透压影响的岩石各向异性渗流模型,使得模型能够更好地表述岩石的变形特性和渗流特性.所建立的模型能够考虑微裂纹闭合摩擦滑移、微裂纹发生自相似扩展和微裂纹发生弯折扩展等过程.
英文摘要：
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-Ⅱ self-similar growth and kinking of closed microcracks under compression and their influences on the mechanical properties of rock are studied in detail.
