摘要
隧道光面爆破是一种控制隧道周边岩体开挖轮廓及超欠挖并且能维持周边围岩稳定的施工技术。文章结合陇布隧道的围岩类型和实际施工情况,对隧道开挖的爆破参数、装药结构和起爆网络,进行了分析与设计;同时对钻爆法施工组织提出了合理的工序安排、质量及安全保障措施。
The tunnel smooth blasting is a technology, tunnel surrounding profite, and can maintain a stability for controlling the exceeding or owing excavation of the the of the surrounding rock after the tunnel excavation. Combining the rock class and the actual construction circs, This article analysised and designed the tunnel blasting parameters , powder charging structure and the blasting network. At the same time, putting forward a reasonable construction organization arrangement and the safeguard measures for quality and safety.
