Based　on　the　completed　large-scale　shaking　table　test　of　liquefaction　free　field,　the　OpenSees　computational　platform　was　used　to　establish　a　numerical　model　of　liquefiable　free-field　shaking　table　test　in　this　study.　In　the　numerical　modeling,　simulation　of　soil　displacement　and　pore　pressure　using　two-phase　fully　coupled　u-p　form.　The　comparison　of　shaking　table　test　results　shows　that　the　established　numerical　model　can　reasonably　simulate　the　seismic　response　of　liquefiable　soils,　and　further　verify　the　reliability　of　the　numerical　model.　At　the　same　time,　the　distribution　characteristics　of　soil　excess　pore　water　pressure　at　the　critical　moment　were　analyzed.　This　paper　provides　an　effective　numerical　method　for　dynamic　response　analysis　of　liquefied　soil.
