【摘要】 文章介绍了在天生桥二级水电站隧硐中用有限元方法进行的岩爆数值预测研究工作。数学模型是在实地分析岩爆破坏机制基础上，经过岩爆强度理论及稳定理论分析，并经过物理模型试验验证后建立的。预测结果与后来隧硐中发生的岩爆实际情况接近。更多还原

【Abstract】 Abstract The rock burst prediction research in the tunnel of the second grade hydraulic power station is given by using the finite element numerical method.Through analyzing rock failure due to rock burst in-situ,applying the rock burst strength theory and the stability theory,and using physical modelling experiment,the mathematical model is built.The predicting result has a good agreement with the rock burst taken place in this tunnel.更多还原
