摘要
探究了隧道开挖施工的爆破振动监测目的、监测内容与监测方法,并对隧道开挖施工阶段的爆破振动技术及要点进行了分析。得出结论:爆破振动监测关乎隧道爆破开挖效果,需要从控制最大装药量、合理应用微差起爆技术、有效控制爆破时差、采用预裂爆破技术等方面进行控制。
This paper probes into the purpose,content and method of blasting vibration monitoring for tunnel excavation construction,and the blasting vibration technology and points of the tunnel excavation construction phase.It is concluded that the blasting vibration monitoring is related to the tunnel blasting excavation effect.It is necessary to control the maximum production capacity,reasonable application of micro-difference explosion technology,effectively control the time difference,and use pre-cracking technology and other aspects.
