To　study　the　impact　of　velocity　pulse　effects　on　liquefiable　sites,　a　finite　element　model　was　established　based　on　the　OpenSees　platform　to　investigate　the　response　differences　of　a　local　liquefiable　site　under　the　near-fault　ground　motions　with　and　without　velocity　pulses,　including　the　vertical　displacement,　acceleration　time　history,　shear　stress-strain　of　soil,　excess　pore　water　pressure　ratio,　and　cyclic　stress　ratio.　The　numerical　calculations　show　that,　under　the　same　amplitude　of　input　ground　motions,　the　average　vertical　permanent　displacement　and　the　duration　of　liquefiable　soil　under　non-pulse　ground　motions　are　13%　and　19%　higher　than　those　under　pulse　ground　motion,　respectively.　The　maximum　shear　strain　of　liquefiable　soil　subjected　to　ground　motions　with　velocity　pulses　is　about　5.　4　times　higher　than　that　of　non-velocity　pulse　ground　motion,　and　the　maximum　shear　stress　is　about　1.　7　times　larger.　Under　the　ground　motions　with　velocity　pulses,　the　liquefiable　soil　exhibits　larger　hysteretic　shear　stress-strain　loops,　but　small　numbers　of　hysteresis　loops,　as　well　as　larger　cyclic　stress　ratio　for　soil　layers　with　different　burial　depths,　which　facilitates　soil　liquefaction.　Moreover,　non-liquefiable　dense　sand　layer　amplifies　the　seismic　accelerations　and　liquefiable　loose　sand　layer　filtered　the　high-frequency　contents　of　the　seismic　ground　motions　leading　to　smoother　acceleration　time　histories　on　the　ground　surface.　Under　the　ground　motions　with　velocity　pulses,　the　excess　pore　water　pressures　are　generally　smaller,　indicating　more　significant　dilatancy　effects　in　the　liquefiable　soil　than　those　under　non-pulse　ground　motions.　©　2024　Beijing　University　of　Technology.　All　rights　reserved.
