摘要
以坂尾隧道Ⅳ级围岩开挖为例,采用普通爆破和光面爆破两种方式进行爆破对比,分析爆后轮廓成型状态、爆破效果,为类似工程选取爆破方案提供参考。
Two blasting methods are applied to the Ⅳ surrounding rock excavation of the Banwei tunnel. The two blasting methods are ordinary blasting and smoothing blasting. By comparing the two blasting methods,the surface profiling state and blasting effect are analyzed after blasting. And it can provide reference for similar projects when selecting the blasting scheme.
