Analysis on Urban Tunnel Blasting Vibration Tests

CHEN Xiao-bin,ZHANG Jia-sheng,YIN Zhi-zheng(School of Civil Engineering & Architecture,Central South University,Changsha 410075,China)  
The blasting vibration tests of Lian-Huang tunnel were carried out and the test results were analyzed in this paper.The test results show that the Sadaovsk formula could well describe the relationship between the vibrating particle's maximum velocity and blasting powder ratio,but the parameters of this formula for the long blasting distance were different from those for short blasting distance.The blasting wave's main frequency was the frequency with low frequency ratio,and the main frequency distribution was different at the different blasting distance.
