Plate　anchors　has　been　widely　adopted　to　provide　uplift　resistance　for　offshore　floating　facilities.　The　research　on　the　bearing　capacity　of　plate　anchors　under　cyclic　loads　is　still　relatively　rare　compared　with　the　monotonic　loads.　In　the　present　paper,　the　bearing　capacity　of　plate　anchors　under　the　combination　of　average　and　cyclic　loads　in　normal　consolidation　clays　with　linearly　increasing　shear　strength　is　investigated　by　performing　finite　element　analysis.　A　more　reasonable　expression　is　proposed　to　determine　the　cyclic　loading　factor　U-cy　by　modifying　the　formula　suggested　by　Det　Norske　Veritas.　A　global　cyclic　loading　factor　U-cy*　is　defined　to　determine　the　cyclic　anchor　resistance　considering　the　difference　of　average　stress　level　for　each　soil　element　around　the　anchor.　The　method　to　determine　U-cy*　by　finite　element　analysis　is　suggested,　and　then　the　U-cy*　for　any　given　normalized　average　loads　and　the　equivalent　number　of　cycles　is　determined.　The　effects　of　the　embedment　depth　and　inclination　angles　on　U-cy*　are　also　investigated　by　performing　a　series　of　numerical　simulations.　An　expression　of　U-cy*　associated　with　normalized　average　loads　and　the　equivalent　number　of　cycles　are　proposed　based　on　numerical　results,　which　can　provide　some　reference　for　the　engineering　design　of　plate　anchors　under　cyclic　loads.
