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.
