摘要
结合具体工程实例,论述了隧道的断面形式及开挖爆破进尺的确定,进行了软岩大断面光面爆破减轻震动设计,给出了具体的设计结果,从而推广光面爆破技术在软岩大断面施工中的应用。
Combined with specific engineering example, the cross section form of tunnel and determination of excavated blasting footage were discussed. The large section smooth blasting to decrease vibration was designed and specific design result was given so as to popularize the smooth blasting in soft rock large section construction.
