摘要

为了研究板岩力学性质，采用细观力学方法对板岩建模进行了研究，并建立了板岩损伤本构模型。在模型中增加了对剪胀变形机制和渗流对变形影响的内容，使得模型能够更好地表述板岩的变形特性。所建立模型能够考虑微裂纹闭合、摩擦滑移、自相似扩展等过程。理论与试验对比结果表明本文模型是适用的。

Abstract

Micromechanics is used in the study of mechanics character of slate. A constitutive model of slate under compression and seepage is established. The process of swelling distortion caused by shearing and seepage are considered for the equations during establishing the constitutive models. The frictional sliding and mode-Ⅱ self-similar growth of closed microcracks under compression and their influences on the mechanical properties of rock are studied in detail. The model is validated by experiment.
