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 In order to realize this dynamical phenomenon of rockburst in underground reconstruction of indoor project, several kinds of simulated materials with high impact were prepared through a large number of tests. The dynamic process of rock burst was reproduced and recorded by self-made loading equipment and displacement sensor The characteristics of the sudden kicking of rockburst are consistent with those of the actual field. The characteristics of the sudden kurtosis of the rock burst are consistent with the terrain deformation of the earthquakes, which can well explain the frequentness of rockburst and the rockburst Before the quiet period
