| 摘 要： | 结合工程实例，在准朔铁路鹰鹞山隧道下石窑斜井土石分界段，提出合理的施工对策和施工方法，即上导V级围岩黄土富水按照“管预支、分部开挖、随挖随护、勤排水、喷闭支撑”，下导软岩采用“微差减震、静态爆破、支护紧跟、闭合成环”的措施，有效地解决了土石分界段施工安全。

| Abstract: | Combining the practical project, and at the kiln inclined tunnel rock boundary stage of the Yingyaoshan tunnel of Zhun-Shuo rail- way, the paper proposes reasonable construcitonal measure and method, that is adopting possession of an advance, excavation division, ground drainage, close support jet to the upper V level surrounding rock loess enriched water, and adopting differential damping, static blasting, keep up with support, closed into a ring to the lower soft rock,so as to solve the safe construction problem in rock boundary stagc. |
