【摘要】 岩爆是地下工程中经常遇到的一种地质灾害，根据二郎山公路隧道在施工中记录的２００ 多次岩爆资料，总结了该隧道岩爆发生的基本规律；并采用“地质超前预报法”、“σθ／ Ｒｂ 判据法”和“岩爆临界深度预测法”三种方法，对其岩爆预测问题作了有益的探讨。更多还原

【Abstract】 As one of the geological hazards,rockburst is often met in underground engineering. In this paper, the basic laws of rockburst in the tunnel of Erlang Mountain road are summarized with more than 200 rockburst incidents recorded during tunnelling. Three effective methods for forecasting rockburst are also discussed. They are geology supertime forecasting,σ θ /R b  judging and rockburst critical depth forecasting.更多还原
