The　stability　of　submarine　pipelines　has　been　extensively　studied　by　coastal　engineers　in　recent　years.　Seismic-induced　pore　pressure　and　effective　stresses　in　the　saturated　porous　seabed　and　pipeline　are　the　main　important　factors　in　the　analysis　of　foundation　stability　around　submarine　pipelines.　The　majority　research　of　the　seismic-induced　dynamic　response　around　an　offshore　pipeline　has　been　limited　to　two-dimension　cases.　In　this　paper,　a　three-dimensional　finite　element　model　including　buried　pipeline　is　established　by　extending　DYNE3WAC.　Based　on　the　proposed　numerical　model,　a　parametric　study　is　conducted　to　examine　the　effects　of　soil　characteristics　and　pipeline　configurations　on　the　seismic-induced　soil　response　around　offshore　pipelines.
