Abstract：

The　damage　of　interlaid　rock　caused　by　blasting　will　affect　the　stability　of　the　adjacent　adjoining　rock　and　tunnel　lining　directly,　especially　in　the　small　interval　tunnel.　Based　on　the　construction　of　Shizishan　Tunnel　in　Nanping,　Fujian　Province,　some　detailed　monitoring　for　the　blasting　vibrations　in　surrounding　rock　mass　and　tunnel　lining　were　carried　out.　According　to　the　measured　data,　the　dynamic　mechanics　parameters　of　adjoining　rock　were　back-analyzed　through　numerical　simulations.　The　velocity　distribution　characteristics　of　interlaid　rock　vibration　in　three　directions　were　well　studied.　Then,　some　conclusions　about　the　interrelation　of　this　three-direction　velocity　can　been　drawn　which　could　provide　some　reference　to　the　blasting　controlling　in　the　small　interval　tunnel.　©　2014　American　Society　of　Civil　Engineers.
