目前我国隧道钻爆法施工存在整体机械化程度较低、施工环境恶劣、工人劳动强度大的问题。以蒙华铁路隧道工程实践为依托，从建立监控量测信息化平台、大断面开挖及初期支护早封闭施工、提高硬岩地段隧道光面爆破水平、确保隧道支护结构质量等方面总结蒙华铁路隧道工程施工技术要点，即“一强化（强化量测）、二紧跟（钢架紧贴掌子面、仰拱紧跟下台阶）、三超前（超前预报、超前加固、超前支护）、四到位（工法选择到位、支护措施到位、快速封闭到位、衬砌质量到位）”；并重点介绍隧道施工机械化配套情况，包括湿喷机械手、自行式仰拱长栈桥、新型二次衬砌台车工装、马蹄形盾构、预切槽设备、悬臂式掘进机等的应用和创新；为全面统筹全线路隧道施工技术管理及提高隧道施工机械化水平形成示范效应并提供技术支撑。

The tunnel constructed by drilling and blasting method has many disadvantages, such as low overall mechanization degree, poor construction environment and high labor intensity. The technical key points of Menghua Railway Tunnel construction, i.e. measurement strengthening, steel frame closes to working face and lower bench followed by inverted arch, advance geological prediction, advance reinforcement and advance support, and proper construction method, rational support method, quick closure and good lining quality, are summarized in terms of establishment of the monitoring information platform, large crosssection excavation and early closure construction of primary support, improvement of smooth blasting level of hard rock tunnel and support structure quality. And then the construction mechanization matching of the tunnel, including the application and innovation of wet spraying manipulator, selfpropelled inverted arch long trestle, newtype of fixtures of secondary lining trolley, horseshoeshaped shield, precutting machine and boomtype roadheader, etc, is emphatically introduced, so as to provide technical support for management of the tunnel construction and improvement of mechanization level.
