【摘要】 基于弹塑性损伤理论,结合格构细胞机以及格构模型的优点,提出了格构细胞机模型,用于模拟岩石的劈裂破坏机理并取得了较好的结果.
【Abstract】 The process of rock splitter is one of the main contents of studies on rock failure mechanisms. Based on elastic-plastic failure theory and the advantages of cellular automata and lattice model, the author presented a model of lattice cellular automata to simulate the mechanisms of rock splitter. And the basic thoughts to simulate rock failure, the methods to express the heterogeneity of rock, AE during rock failure and quantificational curves of stress-strain and AE of rock were introduced in detail. From the simulated experimentations, we could gain the better results.
