  • Increased construction efficiency and safety during blasting operations.

Abstract

随着我国交通基建向西南山区等高海拔复杂地质区域推进,高海拔高地应力隧道工程日渐增多。光面爆 破技术作为该类隧道施工的核心关键技术,对保障施工安全、控制成本、保护周边环境至关重要。本文以水电站相关 隧道工程为背景,通过理论分析、数值模拟与现场试验,系统探究炮孔参数、装药结构、起爆顺序等关键影响因素并 优化设计。结果表明,优化后的参数可有效控制隧道超欠挖、减少围岩扰动,提升施工效率与安全性,为同类工程光 面爆破施工提供重要参考与实践指导。
