摘要: 根據深部采礦巖體變形的離散性特征,運用元胞自動機建模方法構建深部采礦巖體的變形演化模型;利用元胞巖石的狀態變化概率和元胞狀態變化的影響系數,實現深部采礦巖體的動力學模擬.在演化模型的基礎上,進行了模擬實驗,且運用R/S分析法對結果進行分析,得到了以離散度作為巖體穩定性的標準.Abstract: According to discrete characteristics of deformation, an evolution model of deformation in mine rock-mass was built by using cellular automaton (CA). In order to measure the complex process of deformation in mine-rock body, the change probability of cellular rock and the influence coefficient were defined. Simulation tests were carried out and the experimental results were analyzed by use of R/S analysis. It is shown that discrete degree can be taken as the criterion of rock-mass stability.
