The　evaluation　of　the　wave-induced　excess　pore　pressure　around　a　buried　pipeline　is　particularly　important　for　pipeline　engineers　involved　in　the　design　of　offshore　pipelines.　Existing　models　for　the　wave-induced　seabed　response　around　submarine　pipeline　have　been　limited　to　poro-elastic　soil　behavior　and　de-coupled　oscillatory　and　residual　mechanisms　for　the　rise　in　excess　pore　water　pressure.　To　overcome　the　shortcoming　of　the　existing　models,　in　this　study　a　three-dimensional　poro-elasto-plastic　soil　model　with　submarine　pipeline　is　established,　in　which　both　oscillatory　and　residual　mechanisms　can　be　simulated　simultaneously.　With　the　proposed　model,　a　parametric　study　is　conducted　to　investigate　the　relative　differences　of　the　predictions　of　the　wave-induced　pore　pressure　with　poro-elasto-plastic　model.　Based　on　numerical　examples,　it　can　be　concluded　that　the　poro-elasto-plastic　behaviors　of　soil　have　more　significant　influence　on　wave-induced　pore　pressure　of　seabed　around　submarine　pipeline.　As　the　seabed　depth　increases,　the　normalized　pore　pressures　decrease　rapidly　at　the　upper　part　of　seabed,　and　then　change　slightly　at　the　lower　part　of　the　seabed.　Soil　permeability　and　wave　period　have　obvious　influence　on　the　wave-induced　normalized　pore　pressure.　(C)　2014　Elsevier　Ltd.　All　rights　reserved.
