摘要
超欠挖是一个当今隧道开挖施工中普遍存在的现象,直接影响到施工安全及经济效益,而光面爆破技术有效地控制了超欠挖现象,结合拉日铁路盆因拉隧道施工经验,对光面爆破施工技术进行介绍。
Over or under excavation is a common phenomenon found in tunnel excavation, which has a direct impact on construction safety and economical benefits, while smooth blasting technology proves to be an effective counter-measure to this problem. The present paper, in light of the construction experience with the Yinla Tunnel of the Lari Railway Basin, aims to make an elaboration of the employment of this technology.
