Abstract：

This　paper　documents　a　series　of　large-scale　shaking　table　experiments　to　investigate　the　dynamic　response　of　liquefaction　soil.　Test　results　are　discussed　in　terms　of　pore　water　pressure,　earthquake-induced　ground　settlement,　and　acceleration　of　soil.　The　measured　data　show　that,　under　strong　ground　motion,　the　model　foundation　was　more　sensitive　to　the　ground　motion　whose　low　frequency　component　is　more.The　Arias　Intensity　of　ground　motion　was　associated　with　the　peak　of　pore　water　pressure　ratio.　Under　lower　peak　ground　acceleration　(PGA)　ground　motion,　the　magnification　effect　of　acceleration　response　spectra　appeared　at　the　range　of　low-period　component.　However,　in　higher　PGA　ground　motion,　the　model　foundation　shows　obviously　high　frequency　filtering　characteristic.　Observations　in　this　study　may　serve　as　basis　for　engineers　and　researchers.　©　2014　American　Society　of　Civil　Engineers.
