数值模拟软件在岩石力学教学过程中的运用——以颗粒流程序为例

The Application of Numerical Simulation Software in the Teaching Process of Rock Mechanics——Take the particle flow code as an example

岩石力学作为一门新兴的、与工程实践紧密相关的学科,是采矿、土木、水利、能源等专业的主干课程。基于传统岩石力学课程教学过程中存在的原理解释不清、学生对于难点理解困难等局限性,文章采用颗粒流数值模拟程序,以岩石力学中经典的直剪试验和三轴压缩试验为例,介绍如何采用数值模拟方法分析岩石破裂机理及裂纹的演化规律等传统岩石力学教学中学生不易理解的部分。不仅帮助学生在学习过程中对于岩石力学中的重难点有更好的理解,拓展学生创新思维,还帮助教师对岩石的破坏机理进行阐述,提高教学效果。

As an emerging discipline closely related to engineering practice,rock mechanics is the main course of mining engineering,civil engineering,hydraulic engineering,energy engineering and other majors.Based on the limitations of the traditional rock mechanics course,such as unclear explanation of mechanism and difficulties in student's understanding,the numerical simulation program of particle flow code is introduced to analyze the mechanism of rock fracture and the evolution law of cracks,which are not easily understood by student in the rock mechanics learning,taking the classic direct shear test and triaxial compression test as examples in this research.The method can help students to better understand the important and difficult points of the rock mechanics in the learning process and expand their innovative.Besides,it can help teachers to elaborate on the damage mechanism of rock mass and improve the teaching effect.
