A　3D　FEM　stress-deformation　analysis　of　the　concrete-faced　rockfill　dam　(CFRD)　using　the　Wang-Wu　hypoplastic　model　is　presented.　First,　we　analyzed　this　model　and　its　parameters　determined　using　conventional　triaxial　test　curves　of　rockfill　materials,　and　found　out　the　defect　of　this　method　when　applied　to　such　materials.　Therefore,　for　rockfill　materials　used　in　the　present　study,　relationships　of　the　parameters　versus　confining　pressure　were　established　and　the　model　parameters　were　modified　by　using　these　relationships.　We　have　considered　the　rotation　of　principal　stress　axes　and　derived　a　modulus　matrix　of　the　equations　used　in　the　model.　Then,　the　model　along　with　its　modified　parameters　was　applied　to　the　stress-deformation　analysis　of　a　CFRD　using　the　3D　finite　element　method,　and　compared　with　the　Duncan　E-B　model　and　Shen　Zhujiang＇s　double-yield　surface　model.　The　analysis　showed　that,　of　the　main　results　calculated　using　the　modified　Wang-Wu　model,　the　settlement　of　rockfill　was　close　to　that　of　Shen　Zhujiang＇s　model,　and　the　rest　fell　around　those　of　the　Duncan　model,　such　as　the　distribution　of　rockfill　horizontal　displacements　and　the　stress　and　deformation　of　face　slabs　in　storage　period.　Thus,　this　paper　recommends　the　Wang-Wu　model　along　with　the　new　calculations　of　its　parameters　as　presented　above　for　analysis　of　CFRD.　©　2017　All　right　reserved.
