摘　　要：光面爆破技术作为一种有效的爆破控制技术,对施工质量、超欠挖及成本控制至关重要,但是在山岭隧道中经常遇到地下水、岩爆等地质情况,给光面爆破施工带来不便。该文针对该种情况以温泉隧道为背景,从爆破原理、光面爆破参数设计、光爆后效果等几个方面进行探讨,得出合理的施工设计参数,在此基础上提出合理的施工控制技术,为后续隧道钻爆设计提供参考及优化辅助和依据。As an effective blasting control technology,smooth blasting technology is very important for construction quality,over-underexcavation and cost control,but geological conditions such as groundwater and rockburst are often encountered in mountain tunnels,which brings inconvenience to smooth blasting construction.In view of this situation,this paper takes the hot spring tunnel as the background,discusses the blasting principle,the parameter design of smooth blasting and the effect after smooth blasting,and obtains the reasonable construction design parameters.Finally,this paper puts forward the reasonable construction control technology on this basis,so as to provide reference and optimization assistance and basis for follow-up tunnel drilling and blasting design.
