The　sand　gravel　layers　in　Beijing　western　region　are　of　characteristics　of　shallow　burial　depth　and　large　particle　size.　The　influence　of　environment　vibration　induced　by　shield　construction　in　sand　gravel　layer　is　significant.　Field　vibration　tests　were　carried　out　in　an　interval　tunnel　of　Beijing.　Vibration　data　in　construction　process　were　simultaneously　collected　at　buried　strata　points,　ground　points　and　measuring　points　in　tunnel.　The　frequency　domain　characteristics　of　vibration　and　the　rule　of　spatial　attenuation　were　analysed　and　the　environmental　influence　assessment　was　discussed.　It　is　shown　that　the　vibration　is　mainly　due　to　collision　between　cutter　tool　and　gravel　particles.　The　vibration　caused　by　machines　and　transport　vehicles　has　little　effect　on　ground　environment.　The　main　frequency　of　vibration　near　cutter　head　is　mainly　distributed　at　more　than　30　Hz.　The　main　frequency　at　measuring　point　away　from　cutter　head　about　40　m　on　the　surface　of　cross-section　decreases　to　below　20　Hz.　The　vibration　amplitudes　at　measuring　points　are　related　to　the　relative　position　between　cutter　head　and　measuring　points,　whose　levels　are　in　order　as　follows　points　ahead　of　the　cutter　head,　points　on　both　sides　of　the　cutter　head,　points　behind　the　cutter　head.　The　vibration　level　in　vertical　direction　on　ground　near　the　cutter　head　is　about　80　dB　and　it　decays　to　60　dB　away　from　cutter　head　about　20　m　to　30　m.　©,　2015,　Chinese　Vibration　Engineering　Society.　All　right　reserved.
