摘要(Abstract)：

为了探究地应力环境对深部硐室岩爆特性的影响，通过FLAC3D数值模拟软件，建立了高地应力环境下圆形硐室的数值模型，结合硬岩在某个特定围压状态下的实验数据，拟合出了硬岩的极限储能值经验公式，基于岩石应力强度比、弹性变形能岩爆判别指标和相关判据，研究不同地应力环境对岩爆的影响。研究结果表明，岩爆产生的风险和对应的岩爆烈度等级均会受到地应力环境的影响。具体表现为当侧向压力系数λ<1.00时，岩爆会产生在硐室两侧，随着侧向压力系数的增加，岩爆判别指标数值减小，硐室发生岩爆的风险降低；当侧向压力系数λ>1.00时，岩爆发生在硐室的顶部和底部，随着侧向压力系数的增加，岩爆判别指标数值增大，硐室发生岩爆的风险增大。

关键词(KeyWords)： 岩爆特性;地应力环境;侧向压力系数;弹性变形能;岩石应力强度比
