摘 要:介绍了预应力混凝土方桩弹卡式连接件构造和接桩技术,对不同直径的弹卡连接件及锚固筋机械连接件进行了抗拉试验,其强度均满足相关标准要求。对弹卡式连接预应力混凝土方桩进行了接头抗弯、抗剪、抗拉试验,均加载至承载力检验值的110%,且未出现接头破坏的情况,性能指标均满足承载力要求。结合实际工程,对弹卡式连接方桩的桩身完整性和承载力进行了分析,其结果也均满足相关标准要求。Abstract:Thestructureandtechnologyofprestressedconcretesquarepileelasticcardconnectionareintroduced.Thetensiletestofelasticcardconnectionwithdifferentdiametersandmechanicalconnectionwithanchorbariscarriedout,andthestrengthmeetstherequirementsofrelevantstandards.Thejointbending,shearandtensiletestsoftheprestressedconcretesquarepilewithresilientclampingconnectionarecarriedout,allofwhichareloadedto110%ofthebearingcapacitytestvalue,andthereisnojointfailure.Theperformanceindexesofthejointallmeetthebearingcapacityrequirements.Combinedwiththeactualproject,theintegrityandbearingcapacityofthepilebodyareanalyzed,andtheresultsalsomeettherequirementsofrelevantstandards.
