摘要：

According　to　precise　delay　blasting　was　used　in　the　foundation　excavation.　The　nonelectric　detonator　and　electronic　detonator　were　used　in　the　blasting,　the　vibration　which　using　electronic　detonator　area　is　smaller　than　the　electronic　detonator　area;　in　the　second　blasting,　there　is　only　20　m　between　blasting　area　and　structure,　the　precise　delay　electronic　detonator　and　hole-by-hole　blasting　were　used,　near　the　building　set　a　row　pre-splitting　holes,　Vibration　monitoring　results　show　that　the　trend　of　vibration　signals　to　the　high　frequency　part　scattered　which　can　reduce　the　harmful　to　the　building.　The　blasting　vibration　response　spectrum　was　analyzed.　©　2013　Taylor　&　Francis　Group.
