摘要

岩石是经历多次地质运动形成的极为复杂的材料，而蠕变是其典型的力学特征之一，因此，探索模拟岩石蠕变新方法是岩石力学所面临的重要课题。基于八邻居Moore元胞，根据岩石蠕变特征，采用广义能量构造元胞蠕变及破坏演化算法，建立相应岩石蠕变的物理元胞自动机模型，编制相应软件，实现了对细观非均质岩石从稳定蠕变、临界蠕变到加速蠕变特征进行了有效模拟，为进一步研究岩石的蠕变行为提供了一个新的有效途径。

Abstract

Rock is a kind of very complicated medium formed by many geo-actions

creep is a typical mechanical feature for it. To find some new simulating approaches for rock creep is an important task in rock mechanics. Based on 8-neibours Moore cell

an arithmetic of rock creep and failure evolving process is constructed through the broad sense energy dissipation and transmitted from one cell to the others

an effective simulating rock creep model of MH-PCA is built; and corresponding simulating software is compiled. By using the creep MH-PCA software

the process from stable creep

critical creep to the accelerated creep of rock has been simulated effectively. It is valuable for researching the rock creep action ulteriorly.
