| 摘 要： | 高盖山隧道岩爆预测采用工程岩体分级标准判别法、Russenes岩爆判别法、Turchaninov岩爆判别法和Hoek岩爆判别法等4种综合评定判别。当硬质脆性岩类隧道埋深小于240 m时,不会产生岩爆;埋深240~368 m时,可能产生轻微岩爆;埋深368~650 m时,会发生中等规模岩爆;埋深大于650 m时会发生较强岩爆。

| Abstract: | The advanced research of rock burst in the Gaogaishan tunnel is applied by four methods of overall evaluation such as the engineering rock-mass grading standards,the Russenes rock burst discriminance,the Turchaninov rock burst discriminance and the Hoek rock burst discriminance.If the buried depth of the tunnel in hard and brittle rocks is less than 240 meters,it doesn＇t result in the rock burst.If the buried depth of the tunnel is 240 to 368 meters,it is possible to have a light rock burst.If the buried depth of the tunnel is 368 to 650 meters,it occurs a medium-scale rock burst.If the buried depth of the tunnel is greater than 650 meters,it can originate a stronger rock burst. |
