岩体破坏演化的物理细胞自动机(PCA)(Ⅰ)——基本模型

根据岩体的结构与破坏特征，建立了一种新的细胞自动机－－二维物理细胞自动机（PCA）的基本模型，由于该模型考虑了岩体材料的非均质性，非连续性和各向异性等特征，因此，可以有效地模拟岩体的破坏过程，该模型对进一步研究岩体的非线性特征具有重要的应用价值。

STUDY ON PHYSICAL CELLULAR AUTOMATA MODEL OF ROCK MASS FAILURE(Ⅰ)--BASIC MODEL

Based on the structures and failure characters of rock mass,the two-dimensional physical cellular automata (PCA),a new model of cellular automata,is set up. The anisotropy,discontinuity of rock mass,etc,are considered in the model,so the failure process of rock mass can be successfully simulated by the PCA model. The proposed model can be used for valuable reference to study the nonlinear features of rock mass.
