摘要
根据石头河水库防洪抢险道路温家山隧道围岩（f＝6）较为破碎、裂隙发育等特性,通过分析计算确定了光爆参数、炮眼布置和炸药量的控制等,提出了较合理的全断面掘进光面爆破设计,可供同类工程参考.
Based on condition of Wenjiashan tunnel with cracked wall rock （f = 6） and overgrown crevasses, the parameter of blasting with a sleek surface, the collocation of blasting positions and dynamite volume are determined through analysis and computation. So that design scheme for tunnelling with a sleek surface is put forward, which is reasonable and may provide some refrence for similar projects.
