摘要
为了揭示岩石细观尺度破裂演化及其力学特征,研究获得的力学元胞自动机(MCA)方法能够基于能量传递及耗散规则,有效模拟细胞岩石破坏演化过程及其能量释放规律;开发的细观二维颗粒元(2D-ball)模拟方法实现了对煤岩动力过程及其能量变化的有效模拟;研究改进的Boltzmann方法实现了对裂隙煤体内瓦斯运移规律及解吸附特征的有效模拟。
In order to reveal the evolving process of the meso-scale failure of rock and its mechanical features, a mechanical cellular automaton which can effectively simulate the evolving process of cell rock failure and its energy release rule was obtained in the paper based on the rule of dissipation and energy transfer and a 2-D particle element method was developed,which can effectively simulate the dynamic process of coal and rock and its energy variation. An improved Boltzmann method can realize the effective simulation of the gas seepage and the absorption-desorption action in fissured coal.
