Study on Cumulative Damage of Tunnel Shotcrete under Blasting

Abstract:

A prediction model of blasting vibration peak is put forward and analyzed combined with the tunnel blasting in Changxiang highway projection. The attenuation law of blasting seismic wave in tunnel and the evolution law of cumulative damage in concrete layer are discussed in the paper. Furthermore, a detailed analysis of the damage caused by blasting vibration for different bench is presented based on the increment formula of concrete cumulative damage coming from indoor experiment with the vibration monitoring data of Shizilong tunnel, which will play a guiding role for those large-span tunnel constructions in future.
