| 摘 要： | 详细描述岩爆形成过程，总结其特点并对岩爆的影响因素作了系统分析，认为：岩石在具备大量弹性应变能又处在峰值强度以后，处于非稳定的平衡状态，此时再对其施加干扰性因素，则会失稳，在此基础上进一步将稳定性理论应用于岩爆判据分析，工程实例计算表明，该方法能较好地解释许多岩爆现象。

Disturbance response criterion based rockburst analysis |
| |
| Abstract: | A systematic analysis was made of the formation and properties of rockbursts and some affecting factors. It is concluded that with enough elastic deformation energy and beyond the peak strength, rocks are in an unstable equilibrium state. Under such a condition, any minor disturbance will result in the instability of rocks. Besides, the theory of stability was further applied to the analysis of the criterion of rockburst. Practices show that the present method can explain some phenomena in rockbursts and provides a new approach to the study of some complex problems concerning rockbursts. |
