In　order　to　study　the　creep　properties　of　salt　rock　under　low　frequency　cyclic　loading,　creep　tests　on　salt　rock　samples　under　low　frequency　cyclic　loading　are　carried　out　by　adopting　the　loading　mode　of　cyclic　confining　pressure　with　a　constant　axial　stress.　The　test　results　show　that　up　to　a　certain　time,　the　axial　creep　curves　of　salt　rock　are　smooth;　while　after　that　point,　the　axial　creep　curves　clearly　fluctuate　with　the　confining　pressure.　Overall,　the　axial　creep　curves　of　salt　rock　under　low　frequency　cyclic　loading　are　similar　to　that　of　Burgers　model.　According　to　the　connection　relation　of　component　creep　model,　the　Burgers　model　is　divided　into　Maxwell　model　and　Kelvin　model.　The　axial　creep　equations　of　Maxwell　model　and　Kelvin　model　under　the　loading　mode　of　cyclic　confining　pressure　with　a　constant　axial　stress　are　deduced　respectively　in　the　superposition　condition　that　the　fatigue　failure　of　material　is　neglected,　and　the　effect　of　loading　cycle　on　the　models　are　also　analyzed.　Then,　by　combining　the　axial　creep　equations　of　Maxwell　model　and　Kelvin　model,　the　axial　creep　equation　of　Burgers　model　under　cyclic　loading　is　obtained;　and　the　reasonability　of　which　is　verified　by　using　the　creep　test　data　of　salt　rock.　The　result　indicates　that　fitting　curves　and　test　curves　conform　well　each　other;　and　the　proposed　model　can　well　reflect　the　creep　properties　of　salt　rock　under　cyclic　loading,　especially　the　fluctuation　of　creep　deformation　with　loading　change.
