城市浅埋暗挖隧道减震控制爆破施工技术

Damping controlling skill of dynamiting construction of shallow-buried excavation tunnel in city

结合具体工程实例,对城市浅埋暗挖地铁隧道微震控制爆破技术进行了分析研究,总结出一套适用于城市浅埋大断面隧道、小间距隧道、破碎围岩隧道、临近建筑物隧道的爆破技术,以及隧道超欠挖的控制方法。

This paper studies the damping controlling skill of dynamiting construction in tunnel with shallow-buried excavation combining practical projects, and concludes a set of skills that could be applied to tunnel with large cross section, small interval, broken surrounding rocks, and tunnels near to architectures as well as skill of controlling excavate excessively.
