Based　on　the　study　of　the　behavior　of　high　fill　embankment,　the　stress　in　subsidence　on　high　embankment　was　simplified　into　combined　stress,　and　the　creep　settlement　model　of　high-filled　embankment　after　construction　was　established.　By　solving　the　differential　equation　of　the　Kelvin　model　under　cyclic　load,　the　creep　equation　was　established,　and　the　influences　of　the　load　parameters　on　the　calculation　model　discussed.　The　facts　show　that　the　creep　trend　of　Kelvin　model　under　cyclic　load　is　the　same　as　that　under　static　load　with　the　changing　of　time,　and　the　dynamic　creep　strain　is　less　than　the　statistic　creep　strain　during　the　initial　section　and　the　stable　section　in　the　condition　that　the　statistic　loads　are　equal　to　the　maximum　of　the　dynamic　load;　that　with　the　decrease　of　the　frequency　of　cyclic　load,　the　time　that　the　strain　reaches　the　most　in　the　first　cycle　will　increase　and　the　long-term　strain　will　increase　too;　that　the　long-term　strain　which　is　a　linear　function　of　the　amplitude　parameter　of　the　cyclic　load　will　increase　with　the　amplitude　parameter　of　the　cyclic　load;　and　that　the　increasing　speed　decreases　with　the　frequency　of　the　cyclic　load.
