| 中文摘要: |
| 沪昆铁路客运专线新吉坪隧道所处地质条件复杂，区域地质作用剧烈，碳酸岩分布广泛，不良地质特别发育。针对斜井进正洞施工，提出了纵向爬坡导坑法。并以2#斜井为例，介绍了纵向爬坡导坑法施工工艺和斜井进正洞挑顶施工的控制要点，以及在施工过程中的控制量测方法，为新吉坪隧道斜井进正洞挑顶施工提供了技术指导，为类似工程施工提供参考。 |
| 英文摘要: |
| Xinjiping tunnel is located in the complicated geological conditions and has complicated geological conditions, with widely distributed carbonatite and well developed unfavorable geology. According to the construction of inclined shaft into main tunnel, the longitudinal gradient climbing drift method is proposed. Taking the NO.2 inclined shaft as an example, the construction craft and control points and the measurement method are introduced for the roof brushing construction , which provides technological guidance to inclined shaft of Xinjiping tunnel crossing main tunnel and supplies reference to the other similar projects. |
