长大铁路隧道快速施工技术剖析

Analysis of Rapid Construction Techniques of Long and Large Railway Tunnel

以兰渝铁路2标古迹坪隧道项目为依托，详细介绍了在长大铁路隧道中的快速、安全、优质、高效的施工技术，系统阐述了单线斜井断面的优化设计，施工过程中的方案优化以及合理高效的施工组织管理等内容，总结了长斜井长大隧道中采用钻爆法施工技术和专业队伍、设备配套、材料等关键因素组织管理的新经验，为今后类似隧道工程施工提供借鉴作用。

On the basis of the project of Lanzhou-Chongqing Railway,bid package 2,Gujiping Tunnel,the safe,high-effi-cient and quality construction techniques in long and large railway tunnel are introduced in detail.An optimized section de-sign in single-line inclined shaft,optimization scheme and high-efficient organization during construction are illustrated sys-tematically.This paper focuses on summarizing organization experience from construction techniques by blasting method and the key factors of labor,equipments and materials in the long tunnel with long inclined shaft,which can provide the availa-ble information for similar projects.
