| 摘 要： | 运用数值模拟手段 ,对重庆市通渝隧道在大埋深环境下的围岩应力分布特征进行了模拟分析 ,并就可能发生围岩大变形或岩爆的部位进行了预测。模拟计算的结果表明通渝隧道在大埋深环境下在两帮和边拱部位将出现岩爆 ,如果围岩是软弱岩层时 ,则可能发生Ⅱ级以上大变形。 |
| 关 键 词： | 大变形 岩爆 预测 数值模拟 |

| Abstract: | In this paper, using numerical simulation, a study on stress distribution of rock in Chongqing Tongyu Tunnel located deeply under ground was carried out and the areas in tunnel where large deformation or rockburst maybe happen were predicted. The results indicate that when the wall rock in tunnel is a hard rock, the rockburst may occur at sides of tunnel and edge arch, when the wall rock is a soft rock, a deformation larger than II degree one possibly happen in tunnel. |
| Keywords: | large deformation rockburst forecast numerical simulation |
