Analysis of Blasting Vibration for Small Spacing Tunnel Excavation from Field Data
Huayuan Tunnel is one of the small spacing tunnels with worse geological conditions. In the construction, the monitoring way and controlling technology of blasting vibration induced by the tunnel excavation have been studied. Using the regression analysis for the results of monitoring on blasting vibration, the mathematical model of the spread of blasting vibration induced by the tunnel excavation is established. The spread regularity of blasting vibration has been obtained. Combined with the project, the empirical formula of the attenuation of blasting vibration is put forward. Through contrasting and analyzing, the particle vibration velocity can be predicted by the attenuation formula of blasting vibration precisely. This study is used for the guiding of the excavation blasting construction and has been played an important role to assure the safety and quality of the tunnel.
