In　this　paper,　a　large-scale　shaking　table　test　of　the　free　field　with　the　soil　liquefaction　was　conducted　under　horizontal　ground　motion　excitation.　The　temporal　and　spatial　response　of　the　free　field　under　earthquake　excitation　was　analyzed.　The　results　showed　that　when　the　excited　earthquake　was　small,　the　dynamic　response　of　liquefiable　site　and　pore　pressure　ratio　at　different　buried　depths　of　soil　was　small,　whereas　the　peak　acceleration　from　bottom　to　top　enlarged.　This　indicated　that　the　model　foundation　was　in　the　linear　elastic　phase.　When　the　seismic　record　of　0.3g　Wenchuan　earthquake　was　inputted,　the　pore　pressure　accumulated　rapidly　and　the　pore　pressure　ratio　of　the　topsoil　layer　reached　1.　The　model　foundation　showed　obvious　nonlinear　response　characteristics　after　liquefaction.　The　peak　acceleration　in　the　liquefiable　soil　layer　was　not　significantly　enlarged,　while　there　was　an　increasing　trend　of　response　acceleration　from　bottom　to　top.　The　results　of　this　paper　can　be　used　for　comparative　analysis　and　verification　of　numerical　simulation　in　the　future.　©　2019,　Science　Press.　All　right　reserved.
