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。 Through a large number of experiments, a kind of brittle material was selected. The material has a strong impact tendency when it is loaded on a normal testing machine, and a sudden jump occurs when the displacement-time curve is unstable. Can be used as a rock burst simulation material. It laid the foundation for studying the dynamical phenomenon of rockburst indoors. At the same time, the reason of the brittleness of the simulated material was analyzed. Finally, the index of rockburst intensity was proposed through the analysis of the destruction process.
