公路隧道不同围岩下光面爆破技术控制要点

Control Points of Smooth Blasting Technology in Different Surrounding Rocks of Highway Tunnels

文章结合工程实例,介绍了在公路隧道掘进中,钻爆装药采用光面爆破技术,同条件下提高了隧道单循环掘进进尺,加快施工进度,断面开挖质量明显提高,降低了安全风险,创造了可观的经济效益,成果显著,极具推广应用价值。

In this paper,with the engineering examples,the introduction of smooth blasting technology for drilling and blasting charge in highway tunneling is introduced.Under the same conditions,the tunneling schedule is improved and the construction progress is accelerated.The quality of section excavation is obviously improved,Safety risks,and create considerable economic benefits,the results were significant,very promote the use of value.
