摘要
隧道工程在现代基础设施建设中占据重要地位,而岩石力学性能对隧道的开挖、支护等环节至关重要,因此掌握岩石性能测试方法和理解其力学行为十分必要。但随着工程技术的不断进步,传统的岩石力学性能测试方法已逐渐暴露出其局限性。3D-DIC技术作为一种新兴的无损监测技术,具有非接触测量、全场应变测量和高测量精度等优点。通过对岩石单轴压缩实验的详细分析,展示了3D-DIC技术在岩石力学实验中的应用过程,对比了其与传统应变片测量结果的一致性,并借助图像、视频等方式直观展示岩石破坏模式和机理。这不仅激发了学生的学习兴趣,加深了学生对岩石力学的理解,还突出了3D-DIC技术在教学和科研中的重要应用价值。
Tunnel engineering plays a crucial role in modern infrastructure development,and the mechanical properties of rocks are essential for processes such as excavation and support in tunnel construction.Therefore,mastering rock property testing methods and understanding their mechanical behavior is necessary.However,with the continuous advancement of engineering technology,traditional rock mechanical property testing methods have gradually shown their limitations.3D-DIC(Digital Image Correlation)technology,as an emerging non-destructive monitoring technique,offers advantages such as non-contact measurement,full-field strain measurement,and high measurement accuracy.Through a detailed analysis of uniaxial compression experiments on rocks,this paper demonstrates the application process of 3D-DIC technology in rock mechanics experiments,compares its consistency with traditional strain gauge measurement results,and visually presents rock failure modes and mechanisms through images,videos,etc.,stimulating student interest,deepening students'understanding of rock mechanics,and highlighting the significant application value of 3D-DIC technology in teaching and research.
