摘要：

Using　the　soil　static　and　dynamic　universal　triaxial　and　tensional　shear　apparatus,　a　series　of　cyclic　triaxial　shear　tests　under　different　confining　pressures　are　performed　for　saturated　Fujian　standard　sands　with　a　relative　density　of　30%　under　K0-consolidation　condition.　And　compared　with　the　cyclic　triaxial　tests　under　both　isotropic　and　anisotropic　consolidation　conditions,　the　procedure　of　K0　consolidation　and　the　cyclic　shear　characteristic　of　sand　under　different　consolidation　conditions　are　discussed.　The　procedure　of　K0　consolidation　includes　two　stages:　The　gradual　deformation　stage　and　the　steady　deformation　stage.　The　measure　of　the　coefficient　of　earth　pressure　at　rest　K0　is　affected　lightly　by　different　confining　pressures.　And　the　development　of　the　pore-water　pressure　under　different　consolidation　conditions　is　different.　The　dynamic　strength　of　sand　under　K0　consolidation　condition　is　higher　than　the　dynamic　strength　under　anisotropic　consolidation　conditions　(Kc　=　1.67)　and　lower　than　the　dynamic　strength　under　anisotropic　consolidation　condition　(Kc　=　2.94).
