摘要
结合山西坪上应急引水工程引水隧洞14标段的工程实例,介绍了超前导洞与光面爆破相结合的开挖方法,论述了这种施工法的掏槽方式、爆破参数、施工工序及工艺。
Taking No.14 bidding section of the upper diversion tunnel of Shanxiping Emergency Water Diversion Project as example, the authors present the excavation method combing pilot heading hole and smooth blasting, and discuss cutting mode, blasting parameters, construction procedure and technique.
