摘要
本文根据大量现场观测资料研究了青岛地铁施工爆破引起的地面振动效应,分析了炸药类型、药量、爆心距、施工爆破方法以及地质条件等因素对爆破振动效应的影响,总结了青岛地铁施工爆破所引起的地面振动强度的一般规律,为施工中的爆破优化设计和爆破振动控制提供了依据。
With a lot of measuring data in situ, the ground vibration caused by the blastingduring the subway test construction in Qingdao City is studied in this paper. The effects ofsource distance, quantity of powder, ignition sequence, construction method and geologicalcondition etc. on the ground vibration caused by the blasting are carefully analyzed. The general law about the intensity distribution of ground vibration caused by the blasting is summarized, which lays a foundation to find a point of balance between the dig blasting in the tunnel and the city environment on the ground.
