| 摘 要： | 开挖表明，乌鞘岭隧道7号斜井存在软岩问题．从软岩的基本概念入手，确定该软岩类型为节理化软岩，具有岩块强度高，岩体破碎，岩体结构复杂和围岩松动变形受断层、节理等结构面控制等特征．根据其特征，相应地提出超前小导管预支护环形开挖预留核心土的施工对策． |
| 关 键 词： | 乌鞘岭隧道 斜井 软岩 节理化 支护对策 |

| Abstract: | The problem of soft rock is found during excavating the NO.7 slanting shaft of Wuqiaoling tunnel. According to the basic conception of the soft rock,the type of soft rock is determined the jointing soft rock with the characteristics of high rock strength ,fragmentation of rock mass and complex rock mass structure. Also, the looseness and deformation of the wall rock is controlled by the fault and joint.The construction countermeasures of pre-support and cyclicly excavating prepared core soil with advanced small conduit are proposed. |
| Keywords: | Wuqiaoling tunnel slanting shaft soft rock jointing support technology |
