摘要：
The paper used FLAC3D to simulate the impact of the stability evaluation of the highway tunnel lining on the blasting vibration. The field monitoring results were compared with the results of numerical calculation. The results show that the velocity of numerical calculation results and the field monitoring results are in the good agreement, the adopted blasting scheme is safe for the tunnel surrounding rock and its support. According to analysis of simulation results by FLAC3D software, with the blasting area advancing, blasting vibration velocity will have a certain influence on the tunnel. So, in order to ensure the normal production of mine and the safety of tunnel, it is necessary to take effective damping measures and adjust the blasting parameters of mine production.
