| 摘 要： | 本文基于解南高速公路某隧道实测地应力数据研究隧址区初始地应力场分布规律,结果表明隧道区初始地应力场以构造应力为主导。根据实测地应力资料对高地应力区隧道开挖阶段进行岩爆预测,结果显示该区表现为中等岩爆等级。

| Abstract: | Based on the measured in-situ stress data of a tunnel in Jienan expressway, the distribution law of the in-situ stress field in the tunnel site was studied. The results show that the in-situ stress field in the tunnel area is dominated by the tectonic stress. The rock burst in the tunnel excavation stage in the high stress area was predicted according to the measured in-situ stress data, and the result shows that the area is in medium rock burst grade. |
