BLAST VIBRATION INFLUENCE ON EXISTING TUNNELS

摘要

The work on vibration monitoring was between a diversion tunnel for BaiShuiJiang third class power station in YanJin county of YunNan province, and the ShiuBaYan Tunnel underpass of NeiKun Railway. The LS-DYNA explicit dynamic numerical simulation and in situ blast vibration monitoring were used over a short study distance to monitor vibration influence on the existing tunnel by blasting in the diversion tunnel.
