摘要:
依托深汕铁路坪山东隧道工程,开展了聚能管+聚能罩爆破试验,旨在优化隧道开挖爆破效果,控制超、欠挖现象。结合隧道地质条件与围岩特性,阐述了聚能爆破的原理与关键工艺流程。通过现场爆破试验,分析了不同周边眼间距与单孔装药量对爆破效果的影响,并对比评估了经济成本。结果表明:在节理化砂岩地层中,通过调整爆破参数,聚能爆破显著提升了掌子面质量,明显改善了超、欠挖现象;超、欠挖体积分别从35.35、 0.33 m3降至4.74 m3和0.13 m3,较传统爆破方式大幅减少。与传统爆破相比,聚能爆破每个循环可节省15~20发雷管和8~9 kg炸药,材料成本降低401~534元,钻孔数量和施工时间明显减少,展现了较高的经济效益与施工效率。
