| 摘 要： | 某新建隧道位于两条既有平行隧道中间,隧道走向与既有隧道平行,净间距为5m,路线全长1098m,为全程小间距隧道,施工难度较大。本文通过现场试验和测试,参考岩石破坏的最大峰值速度,确定了快速施工的开挖方案和爆破参数,并通过该工程对爆破分级提出了一些建议。

| Abstract: | With a total length of 1098m and net space of 5m, the new tunnel to be build was located between two existing paralleling tunnels, which was hard to be constructed owing to the small space all the way. The present paper established the program of fast construction and blasting parameters through site tests and measure- ments by consulting the peak particle velocity of blast-induced damage, and meanwhile, it put forward some ideas of blasting classification regarding this project. |
