At　present,　slope　anchor　frames　are　often　regarded　as,　a　plane　bending　member　to　merely　sustain　the　component　of　the　tensile　force　of　the　anchors　perpendicular　to　the　axises　of　the　frame　at　the　intersections,　same　as　the　cross　foundation　beam　on　a　flat　ground.　Their　internal　forces　are　calculated　using　the　Winkler　elastic　foundation　beam　method.　They　are　actually　a　combined　deformation　member,　sustaining　bending　combined　with　tension　or　compression　deformation　or　skew　bending　when　the　influence　of　skin　friction　from　the　soil　at　the　bottom　of　the　frames　and　axial　loads　are　ignored.　As　a　result,　there　exists　a　deviation　between　the　calculated　results　and　the　real　values.　For　this　purpose,　taking　a　cutting　slope　of　loess　as　an　example,　a　finite　element　method　for　computing　the　internal　forces　of　slope　anchor　frames　was　originally　established.　The　action　of　anchors　is　simplified　as　an　equivalent　force　and　the　influence　of　the　skin　friction　and　axial　loads　is　considered.　Meanwhile,　the　corresponding　parameters　in　the　link　finite　element　model　based　on　the　Winkler　method　were　converted　using　the　deformation　modulus　of　the　loess.　The　current　method　was　used　to　analyze　the　existing　problems　of　the　Winkler　method　as　well　as　the　result　differences　from　those　by　the　simplified　finite　element　model　of　the　slope　anchor　model,　the　solid　finite　element　and　link　finite　element　models　for　a　frame　on　the　flat　ground　were,　respectively,　established.　The　results　show　that　for　the　models　on　the　flat　ground,　the　bending　moment　diagrams　of　the　vertical　ribs　by　the　Winkler　method　were　quite　similar　to　those　by　the　solid　finite　element　method,　but　the　maximum　moment　of　the　former　was　greater　than　that　of　the　latter.　The　bending　moment　of　the　horizontal　beams　were　significantly　different.　It　is　also　shown　that　there　will　be　a　significant　deviation　from　the　actual　internal　forces　when　the　frame　with　combined　deformation　on　a　slope　is　regarded　as　a　frame　with　plane　bending　on　a　flat　ground.　©　2023　Editorial　Office　of　China　Civil　Engineering　Journal.　All　rights　reserved.
