摘要
根据岩石的破裂机理，本文提出了在单轴压力下的全应力应变关系的微观破裂模型。该模型是以三种变系数Ｋ（ε，ｘ）、Ｒ（ｘ）、Ｂ（ｘ）分别所对应的弹簧元件、滑动元件及断裂元件为模型的基本元件组成单位块体模型。模型模拟变形和累进破裂中的应力应交关系。
According to cracking mechanism of rock, this article presents a model of complete stress-strain under uniaxial compress in minute cracking. The model has made use ofelastic,sliding and fracturing elements with variables K (ε, x), R(x) and B (x ) respectivelyto constitute unitizing modules. It analogizes the stress-strain relation between deformationand repeated crabing.
