长大隧道机械化配套安全快速施工技术

Rapid Mechanized Construction Techniques for Long Tunnels with Large Sections

文章以贵广铁路天平山隧道工程实践为例,从超前地质预报、开挖与支护、装碴与运输以及仰拱施工、防排水、二次衬砌等方面,详细地介绍了铁路隧道机械化配套技术,以及自动定位安全预警系统的配置,并对实现掌子面人员安全跟踪定位及信息化管理、实现长大隧道安全快速施工进行了探讨。

Using the construction of the Tianpingshan tunnel on the Guizhou-Guangzhou railway as an example, this paper discusses the configuration during the mechanized construction of tunnels related to advanced geological prediction, excavation, preliminary support, mucking, invert construction, waterproofing, water drainage, and secondary lining. With an automatic safety pre-warning system, it is possible to realize tracking, positioning, and information management and achieve rapid and safe construction of long tunnels with large sections.
