The　shaking　table　test　of　buried　pipelines　under　multi-point　non-uniform　excitation　is　carried　out　to　investigate　the　nonlinear　seismic　response　of　site　soil　with　the　use　of　a　nine　sub-table　array　shaking　table　system　in　Beijing　University　of　Technology.　Through　experiments,　the　macroscopic　phenomena,　the　dynamic　characteristics,　and　the　acceleration　response　of　site　soil　during　vibration　were　observed.　Also,　the　seismic　response　characteristics　and　variation　of　the　soil　under　different　earthquake　motions　and　different　seismic　intensities　were　studied.　The　acceleration　amplification　factor　of　the　free-field　and　non-free-field　soils　and　the　acceleration　time　history　and　Fourier　spectrum　of　the　same　measuring　point　were　compared.　The　results　show　that　the　seismic　response　of　the　soil　is　not　only　related　to　the　ground　motion　record　and　the　loading　level,　but　also　has　a　relationship　with　the　buried　structures.　The　damping　ratio　and　the　basic　frequency　of　the　non-free　field　are　larger　than　the　parameters　of　the　free　field.　The　seismic　response　of　the　pipeline　is　basically　subordinate　to　the　response　of　the　soil　under　lower　loading　level,　but　with　the　increase　of　loading　level,　the　restraint　effect　of　soil　decreases,　and　the　acceleration　of　the　pipeline　is　slightly　larger　than　that　of　the　soil.　The　existence　of　the　buried　pipeline　has　a　certain　influence　on　the　dynamic　characteristics　of　the　soil　within　a　certain　range,　but　if　the　location　is　beyond　that　range,　the　impact　will　be　rapidly　weakened.　The　conclusions　obtained　are　consistent　with　the　macroscopic　phenomena　of　seismic　response　obtained　by　the　test,　which　corroborated　each　other＇s　rationality.　Furthermore,　the　conclusions　support　the　analysis　of　seismic　damage　mechanisms　of　subsequent　buried　pipelines.　©　2020,　Science　Press.　All　right　reserved.
