| Abstract: | Along with extensive application of New Austria Tunneling Method in construction of expressway tunnels,the smooth blasting technologies in support for such application are attracting more and more attentions from engineering and technical personnel.The advantages of New Austria Tunneling Method can be better realized and the loading capacity of wall rocks can be better brought into display only when smooth blasting is properly carried out.In this paper,from the several aspects such as smooth blasting mechanism,smooth blasting parameter selection and smooth blasting influential elements,it is introduced how to improve smooth blasting efficiency so as to save engineering costs. |
