关于单线铁路长隧道快速掘进施工技术的探讨

Discussion on the fast heading construction technology in long single-track railway tunnels

针对如何实现长隧道的快速掘进这一问题,在简要介绍隧道爆破技术研究进展和钻爆法施工作业过程的基础上,阐述了单线隧道爆破掘进技术的特点及发展方向,总结了我国目前隧道爆破工程中存在的问题。

As for how to realize the fast heading of the long tunnels,this paper elaborates on the characteristic and development trend of blasting tunnel technology in single-track railways based on a brief introduction of the development of the study on tunnel blasting technique and the drill plus blast technology and concludes the existing problems in the course of blasting tunnel.
