摘要
传统的室内岩石力学实验只能提供岩石的宏观力学参数和岩石试样宏观破坏特征,不能获得岩石实验加载过程中,组成岩石试样的内部颗粒细观参数的时-空演化关系,不利于学生对岩石相关宏观力学参数和破坏模式的理解。将颗粒流软件PFC2D引入岩石力学压缩实验教学,通过室内实验和数值实验的双重训练,能够使学生从岩石的微观组构特征角度认识岩石力学的特性差异,拓展了思维,开阔了眼界,提升了科研兴趣,取得了较好的教学效果。
The traditional indoor rock mechanics experiment can only provide the macro mechanical parameters of rock and the macro failure characteristics of rock samples,and cannot obtain the time-space evolution relationship of the internal particle micro parameters of rock samples during the loading process of rock experiments,which is not conducive to students'understanding of the relevant macro mechanical parameters and failure modes of rock.The introducing of particle flow software PFC2D into the experimental teaching of rock mechanics compression,through the dual training of indoor and numerical experiments,it can enable students to understand the characteristics difference of rock mechanics from the perspective of rock micro fabric characteristics,expand their thinking,broaden their horizons,enhance their interest in scientific research,and achieving good teaching results.
