摘　　要：云雾山隧道为宜万铁路线八大长隧道之一,地质条件不良,光面爆破开挖施工难度较大。通过对云雾山隧道工程实地调查,分析光面爆破效果影响因素。结合施工技术经验,研究制定隧道光面爆破的参数选择、炮眼布置、装药结构、质量控制内容。经实际工程证明,采用该施工技术爆破效果良好,具有重要的工程借鉴意义。The Yunwu mountain is one of the eight long tunnels of Yi-wan Railway Line. Due to poor geological conditions, the smooth blasting excavation construction is full of difficulty. Through a field investigation of the Yunwu mountain tunnel project, this paper analyzes the effect of smooth blasting influence factors. Combined with the experience of construction technology, this paper also sets up the tunnel smooth blasting parameters selection, hole arrangement, charge structure, and contents of quality control. It is proved by actual project that the blasting effect of construction technology is excellent and is of great reference value for similar projects.
