摘要
针对岩石力学室内实验在传统教学过程中存在的局限性,提出建立岩石力学数字实验教学平台作为辅助教学手段。该数字教学平台采用颗粒流程序PFC构建,内容包括岩石的三轴压缩强度试验、劈裂强度试验、直剪试验及单轴抗压强度试验。该平台可形象和直观地展现岩石试样在外荷作用下的变形和破裂过程、应力应变关系及内力变化,并可进行实时操作和制作成动画进行讲解。这对于提高学生对实验的兴趣、加深理论知识的理解和拓展数值分析能力具有重要意义。
A digital experimental platform for rock mechanics was proposed as an assistant education to remedy the disadvantage of the traditional rock mechanics experiments. The platform was built using Particle Flow Code( PFC),which compress,and uniaxial compression test. It could exhibit the whole procedures of deformation and fracture,stress and strain relationship,and the change of internal stresses in specimens. In addition to the real-time operation,the platform could also be made animation for teaching. The results of the education reform were of significance for undergraduates to enhance the interests in experiments,improve the understanding of the theory,and develop the knowledge of numerical analysis.
