Analysis of Vibration Effects of Shallow Highway Tunnel under Blasting Seismic Waves

摘要

According to blasting excavation instance on the top of shallow highway tunnel in Pingyikou Industrial Park 270 platform Project of field,analyzing the effect of blasting vibration to the shallow highway tunnel.In order to ensure the safety of the tunnel,monitoring in real-time vibration velocity of tunnel blasting by using TC-4850 vibration meter.And for safety reasons,determine the security of the structure referring to the allowed maximum safety velocity of the general brick and large blocks of non-seismic building,and give improving advices to the follow-up blasting design and construction.
