Calcareous　sand　is　widely　used　in　coastal　engineering　and　island　construction,　which　has　the　characteristic　of　easy　crushing.　A　series　of　ring　shear　and　one-dimensional　compression　creep　tests　were　carried　out　for　the　crushing　evolution　under　the　influence　of　large　deformation　and　time　length　effects.　The　mechanical　characteristics　and　deformation　properties　of　the　single-graded　specimens　were　analyzed,　focusing　on　the　crushing　characteristics,　and　fractal　properties　under　the　action　of　different　shear　displacements,　stress　levels,　initial　gradations　and　creeping　motion　effects.　The　results　show　that　the　fractal　dimension　is　positively　correlated　with　crushing,　the　increase　of　shear　displacement,　stress　level,　and　initial　mean　particle　size　has　a　facilitating　effect　on　crushing.　Under　large　deformation　conditions,　this　promoting　effect　gradually　tends　to　slow　down,　and　the　characteristic　of　limit　fractal　exists.　The　creep　behavior　reflects　the　continuous　deformation　characteristics　of　calcareous　sand,　and　the　specimen　as　a　whole　is　still　in　the　stage　of　crushing　development,　and　the　effect　of　time　duration　on　the　fractal　is　limited.
