微地震精细爆破技术在2扩4隧道开挖施工中的应用
|
摘要
本文依托于隧道扩挖工程实践介绍了微地震精细爆破技术的重要性。介绍了精细爆破的技术研究、爆破设计、器材选型、施工技术、施工管理以及爆破效果评价等内容。通过具体隧道扩挖工程实践,将爆破的计算理论、设计原则、钻爆参数以及减震措施等进行介绍,对具体工程进行监测和数值分析。最后本文还对应用的效果进行了总结。
This article relies on the tunnel excavation practice expansion introduces the importance of micro-seismic fine blasting. The technical research,blasting design,equipment selection,construction technology,construction management and evaluation of fine blasting blasting effect and so on. Concrete tunnel dug by expanding engineering practice,theory of computation will be blasting,design principles,drilling and blasting parameters and damping measures are introduced,the specific project monitoring and numerical analysis. Finally,this paper also summarizes the effect of the application.
