摘要:
为了提高水平岩层隧道光面爆破效果,减少隧道爆破开挖超欠挖量,提高施工速度和减少工程投资,以段家坪隧道为例,采用数值模拟和现场试验对聚能爆破在隧道开挖成型控制中的作用进行研究。数值模拟结果表明,聚能结构一侧上的围岩节点振动速度和单元应力均大于非聚能结构一侧。现场聚能爆破试验表明,周边眼聚能装药结构能够更好地控制水平砂泥岩地层隧道爆破成型,大部分超挖量控制在15 cm以内,最大超挖量减少了78.9%。
Abstract:
In order to improve the smooth blasting effect of horizontal rock tunnel, reduce the overbreak and underbreak, increase the construction speed and reduce the project investment, by taking Duanjiaping tunnel as an example, the control of shaped charge blasting in tunnel excavation was studied by numerical simulation and field test. Numerical simulation results show that vibration velocity and unit stress of surrounding rock particles on one side of the energy-accumulating structure are greater than those on the other side of the non-energy-accumulating structure. Field tests show that the surrounding eyeball shaped charge structure can better control the blasting formation of tunnels in horizontal sand and mudstone strata. Most of the over-excavation was controlled within 15 cm, and the maximum over-excavation is reduced by 78.9%.
