摘要
通过大量实验选取了种脆性材料，该材料在普通试验机上加载测试观察其具有较强的冲击倾向，位移—时间曲线失稳时产生突跳．可用来作岩爆模拟材料．为室内研究岩爆这一动力现象奠定了基础，同时，分析模拟材料产生脆性的原因，最后，通过破坏过程分析提出了岩爆烈度的指标。
Based on a large number of experiments,several brittle materials are selected to be used as simulating materials fol rockbursts. It is proved that these materials have relatively strong shock tendency. It is also found that there is a sudden increase in its deformation when the unstable failure occurs all of these shows that these materials can be taken as simulating materials for rockburSts in this peper,the index for rockburst strength is established based on the study of complete failure process.
