铁路软弱围岩隧道施工技术分析

Analysis on Construction Technology of Railway Tunnel in Weak Surrounding Rock

现如今,我国铁路在对大断面软弱地质围岩隧道进行施工时,具备一定的潜伏性,且施工时间长,技术繁琐,地质条件的不可预见性随之增强,介绍了在建成贵铁路高坡隧道为例重点描述在软弱复杂地质条件下软岩大变形段施工中的加强措施及控制要点。

Nowadays, the railway in our country has certain latency in the construction of large-section tunnel with weak geological surrounding rock, and the construction time is long, the technology is cumbersome, and the unpredictability of geological conditions is enhanced. This paper briefly describes the strengthening measures and control points in the construction of high-slope tunnel of Guizhou Railway as an example, focusing on the construction of large deformation section of soft rock under soft and complex geological conditions.
