摘要

提出了一种模拟岩石破坏过程的细胞自动机模型，以力、位移作为基本状态变量，基于基本的力学规律构造了细胞自动机模型的矢量局部更新规则，克服了以往规则确定随意性以及标量化的缺点。利用该模型模拟了岩石的单轴破坏过程，研究了非均质性对单轴直接拉伸破坏过程的影响，并研究了几何形状（长宽比）对单轴拉伸强度的影响，研究结果加深了对岩石单轴抗拉强度的了解，对试验有一定的指导作用，应进一步加强岩石的直接拉伸试验研究。

Abstract

A cellular automaton method is presented to simulate rock failure. Force and displacement are taken as the basic state variables. Based on the basic mechanical laws vector updating rules are constructed

which overcomes the shortcomings of arbitrary decision of local rules and scalar variables. Based on this cellular automata model

rock failure process is simulated under uniaxial tensile conditions. And the influences of heterogeneity and sample shape on uniaxial tensile strength are studied. The results reveal uniaxial tensile behavior of rock and guide the uniaxial tensile experiments.
