| Abstract: | Smooth blasting is a technology to make the rock surface smooth after blasting through controlling the forces and directions of blasting.It can prevent rock cracking,increase stability of the surrounding rock,decrease blasting vibrations perturbation on surrounding rocks,so as to control the outline of rock excavation.In light of the drilling and blasting construction practice of YQ5 Bid Tunnel weak surrounding rock in Luo-Zhan Railway Hongcen Section,this paper introduces the application of smooth blasting in the drilling and blasting excavation of tunnel weak surrounding rocks. |
