In　this　study,　we　proposed　a　novel　method　to　extract　pore　pressure　model　parameters　from　vertical　array　seismic　records　and　pore　water　pressure　data,　building　upon　the　existing　method　for　estimating　in-situ　soil　dynamic　parameters.　Using　the　extracted　in-situ　soil　properties,　one-dimensional　effective　stress　analysis　is　conducted　in　DEEPSOIL　to　reproduce　and　predict　the　nonlinear　ground　response　and　pore　pressure　variations　at　the　Wildlife　Liquefaction　Array,　California.　Our　results　show　that:　(1)　the　increase　and　dissipation　process　of　excess　pore　water　pressure　can　be　well　empirically　modeled　using　the　Hill　Equation　and　an　exponential　decay　function,　respectively;　(2)　the　simulated　ground　response　and　pore　pressure　variations　using　in-situ　soil　properties　are　consistent　with　the　observations,　which　demonstrates　the　feasibility　and　effectiveness　of　using　in-situ　soil　properties　to　predict　pore　pressure　variations　during　strong　motions;　(3)　effective　stress　analysis　does　not　outperform　total　stress　analysis　in　ground　response　analysis　when　the　excess　pore　water　pressure　ratio　(ru)　is　no　greater　than　0.6,　but　can　be　used　to　evaluate　the　potential　for　liquefaction　triggering;　(4)　when　simulated　ru　＞　0.9,　there　are　clear　differences　between　the　simulated　ground　motions　using　total　stress　and　effective　stress　analyses　at　this　site.　©　2025
