摘要
根据大量工程岩爆实例,总结抛掷型岩爆的特征,提出了一个剪切抛掷型岩爆的简化力学模型,对抛掷型岩爆发生的物理力学过程进行研究。研究结果表明:岩石系统的稳定性首先取决于围岩系统内部的刚度分布。
Based on a large number of engineering rockbursts,the characteristics of projectile rockbursts are summarized,a simplified mechanical model of shear projectile rockbursts is proposed,and the physical and mechanical process of projectile rockbursts is studied.The results show that the stability of the rock system first depends on the stiffness distribution within the surrounding rock system.
