Abstract
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.关键词
