新建川藏铁路隧道钻爆法机械化配套快速施工研究

新建川藏铁路隧道占比大、特长隧道及隧道群密集,高海拔隧道占比大,只有采用大型机械化配套技术,才能达到快速施工,以机代人,满足建设的要求。本文通过对现有隧道机械化施工为依据,分析当前隧道机械化配套施工存在的问题,研究并提出川藏铁路一次建成长大隧道集群应满足的机械化配套方案、解决影响施工进度的措施、施工进度指标、高原长距离施工供氧方案、通风方式以及智能建造装备配套管理等,为高起点、高质量建好川藏铁路高原隧道提供了参考意见和建议。

Research on Mechanized Supporting Rapid Construction by Drilling and Blasting Method in Newly-built Sichuan-Tibet Railway Tunnel

The proportion of tunnels in newly-built Sichuan-Tibet Railway is large,the extra-long tunnels and tunnel groups are dense,and the proportion of high-altitude tunnels is large.Only by adopting large-scale mechanized matching technology,can we achieve rapid construction,replace people with machines and meet the requirements of construction.With the existing tunnel mechanization construction,this paper analyzed the problems existing in the current tunnel mechanization construction,studied and put forward the mechanization matching scheme that should be satisfied when the Sichuan-Tibet Railway is to build a long and large tunnel group at one time,the measures to solve the problems affecting the construction progress,the construction progress index,the plateau long-distance construction oxygen supply scheme,the ventilation mode and the matching management of the intelligent construction equipment,etc.,it could provide reference opinions and suggestions for the construction of plateau tunnel of Sichuan-Tibet Railway with high starting point and high quality.
