岩爆的物理模拟及其机制的研究

STUDY ON ROCK BURST BY MEANS OF PHYSICAL SIMULATION

摘要: 为实现室内再现地下工程中岩爆的这一动力现象,通过大量的试验配制出几种冲击性较强的模拟材料,利用自制的加载设备和位移传感器,再现了岩爆的动力过程,并记录了岩爆的位移突跳这一特征,所得到的结果与现场实际相吻合,岩爆的位移突跳特征与地震的地形变具有一致性,较好的解释了岩爆的频繁性和岩爆前的平静期。

Abstract: To study the mechanism of underground rock burst,the dynamic process of rock burst has been simulated in the laboratory.Pressuring device and displacement sensor used for testing were made of ourself.The testing results conform with practical occurrence of rock burst.
