This　paper　took　the　Zhongyinggong-Xiaoxigou　segment　of　Xinjiang　Urumqi　Line　1　subway　tunnel　as　the　engineering　background.　By　conducting　several　vibration　monitoring　tests　on　the　subway　tunnel　surface　it　was　found　that　hollow　effect　phenomenon　existed　in　the　monitoring　range　of　16　m　before　and　behind　the　tunnel　face　of　the　shallow　subway　tunnel.　As　the　measure　points　got　further　from　the　tunnel　face,　hollow　effect　phenomenon　showed　the　tendency　of　going　up　first,　declining　later,　and　disappeared　finally.　In　this　paper,　lagrange　algorithm　and　complete　restart　were　adopted　to　simulate　the　blasting　of　subway　shallow　tunnel　using　LS-DYNA　program.　It　showed　that　hollow　effect　phenomenon　existed　in　the　range　of　10　m　before　and　behind　the　tunnel　face　of　the　shallow　subway　tunnel;　this　phenomenon　was　most　significant　at　the　point　of　6　m　before　and　behind　the　tunnel　face.　By　changing　the　blasting　of　the　cut　hole　charge　into　multi　section　blasting,　the　single-stage　detonation　dose　and　the　surface　vibration　effect　were　reduced.　It　not　only　ensured　the　safety　of　subway　construction　but　also　effectively　controlled　the　impact　of　tunnel　blasting　construction　on　surrounding　buildings.　©　2018,　Editorial　Department　of　Transaction　of　Beijing　Institute　of　Technology.　All　right　reserved.
