摘　　要：为了研究深路堑石方开挖光面爆破技术,以某高速公路为研究背景,对光面爆破技术的设计原则、施工参数、装药结构、安全技术措施、爆破效果进行了分析.结果表明:在深路堑石方开挖中科学合理地应用光面爆破技术,炮眼痕率和超挖、欠挖量都在允许范围值中,不会对周围环境和建筑物造成影响,既能有效提升开挖施工的效率,还能有效保证施工的安全性和爆破效果.In order to study the smooth blasting technology for deep cutting stone excavation, the design principle, construction parameters, charging structure, safety technical measures and blasting effect of the smooth blasting technology are discussed with a highway as the study background. It is concluded that the smooth blasting technology can be applied scientifically and reasonably in deep cutting stone excavation. The blast-hole trace rate, over-excavation and under-excavation are within the allowable range, which will not affect the surrounding environment and buildings. The efficiency of excavation construction is effectively improved, the safety of construction and blasting effect of the conclusion can be effectively ensured as well.
