At　present,　grouted　sleeve　connections　are　mainly　used　in　the　form　of　assembled　structural　connections　at　home　and　abroad,　and　the　construction　of　grouted　sleeve　is　usually　carried　out　above　5.　However,　due　to　the　influence　of　temperature　and　construction　period,　the　research　on　the　mechanical　properties　of　grouted　sleeve　connections　in　low　temperature　environment　is　demanded.　In　this　paper,　the　numerical　model　of　semi-grouted　sleeve　specimens　with　different　grouting　defects　under　low-Temperature　environment　was　established　by　the　method　of　finite　element　numerical　simulation,　and　the　stress　distribution　maps　of　the　finite　element　simulation　of　semi-grouted　sleeve　specimens　with　different　grouting　defects　under　axial　load　were　obtained　and　their　numerical　characteristics　were　analyzed.　©　2024　ACM.
