摘要
结合现场实际施工情况,介绍如何解决水平岩层大断面隧道施工中光爆开挖超欠的问题,以及如何提高长大隧道的掘进速度,提出了"岩变我变"的思想,提高光爆效果。
Integrating site-construction situation,this thesis introduces the way of how to solve the overexcavation problem in the smooth blasting technology of large-section tunnel of plane terrane,and how to speed the driving speed in long-huge tunnel.Finally,it proposes the idea of ＂Rock changes and I change＂ so as to improve the light blasting excavation effect.
