摘　　要：从微观角度分析了圆形硐室片帮型岩爆发生机制。用灰绿色闪长岩模拟了双向受载下硐室岩爆的发生 ,记录岩爆发生过程中的声发射 ,二者在一定程度上具有一致性。提出了监测方法以及对岩爆的防治措施。The mechanism of splitting type rock burst of round chamber is analyzed from microcosmic viewpoint.The rock burst of chamber under bi directional load was simulated with sage green diorite and the acoustic emission in the process of rock burst was recorded.The coherence between them was found to a certain degree.The preventive measures and the monitoring methods of rockburst are suggested.
