随着岩石力学教学不断发展进步,应用真三轴实验设备进行教学具有局限性,该文建立了虚拟仿真实验教学平台,并利用该平台进行真三轴实验教学,达到了良好的教学效果。该虚拟仿真实验由教师提供实验技术要求,搭建可视化虚拟仿真用户界面,使学生深刻理解硬岩真三轴加载系统的性能参数、岩石试件真三轴应力-应变曲线测试过程以及声发射微观监测技术在岩石力学真三轴实验中的应用。学生可以通过虚拟平台便捷、直观地完成真三轴实验操作,有效解决实验设备不足、实验操作不安全等问题,有利于学生将理论学习与实践操作结合,提高学生对岩石力学专业知识的理解,对培养岩土领域人才具有重要促进作用。

With the continuous development and progress of rock mechanics teaching, the application of true triaxial experimental equipment for teaching has limitations. This paper establishes a virtual simulation experimental teaching platform, and uses this platform for true triaxial experimental teaching, achieving good teaching effect. In virtual simulation experiment, teachers provide experimental technical requirements and build a visual virtual simulation user interface, so that students can deeply understand the performance parameters of real triaxial loading system of hard rock, testing process of real triaxial stress-strain curve of rock specimen and application of acoustic emission micro monitoring technology in real triaxial experiment. Through the virtual platform, students can easily and intuitively complete the real triaxial experiment, effectively solve the problems of insufficient experimental equipment and unsafe operation, which is conducive to the combination of theoretical learning and practical operation, improves students’ understanding of rock mechanics professional knowledge, and plays an important role in promoting the training in the field of rock and soil.
