摘　　要：利用虚拟现实技术将单轴压缩实验采集的应力应变实验数据和声发射系统采集的声发射信息,与岩石试件的三维模型和岩石破裂面的宏观信息全部集成到同一虚拟场景中,不但可以为学生提供观察各种实验数据的一种可视化手段,而且可以对岩石破裂过程中的声发射事件进行形象直观的动态模拟显示。这将有助于加深学生对岩石破裂实验的理解,对岩石力学课程的教与学具有非常重要的意义。By way of the virtual reality technology,the stress and strain experimental data collected from the uni-axial compression experiment and the acoustic emission information collected by the acoustic emission system are integrated into a virtual scene together with the three-dimensional model of rock specimen and affiliated surface information.It provides students with a visual means to observe various experimental data and implement a dynamic simulation of acoustic emission events during rock failure.It can help students deepen their understanding of rock failure experiments and is of great significance to the teaching and learning of rock mechanics.
