隧道软弱围岩钻爆施工方法

The Construction Method of Tunnel Soft Surrounding Rock Drilling and Blasting

通过对隧道软弱围岩爆破施工的炮眼布置、参数设置、装药量控制等方面进行合理设计,即提高了循环进尺,又使超欠挖现象得到了有效的控制。使隧道施工更合理、更科学、更安全,为隧道钻爆施工起到了指导作用。

This paper reasonably designed the shot hole arrangement, parameter setting and charge control etc. of tunnel soft surrounding rock blasting construction, which improved the circulation footage and made the overbreak phenomenon be controlled effectively. It also made the tunnel construction more reasonable, more scientific, more safe, and had a guiding role for the tunnel drilling and blasting construction.
