《河南水利与南水北调》2022年第12期试验与研究某泵站工程桩基水平荷载试验研究黎伟林(深圳市水务工程检测有限公司,广东深圳518000)摘要:以水利工程泵站为例子,在场地开展了泵站施工桩基水平荷载试验,对桩体受到水平力时的变形特点进行了研究和分析,研究结果表明:此场地将水平位移最大值定为6mm是十分合理和安全的,除此之外,设计时选取位移控制和选取水平承载力控制相比,前者更加科学合理;桩的力学响应因为各自位置和离坡脚远近的不同而表现出较大的差异,呈现出水平承载力随坡脚距离的减小而增大;垂直分力作用于边坡土体上,会使桩身受到比较高的球应力,在一定程度上提高了整体的抵抗能力;土质边坡有着均匀性的特征,和岩质边坡坡体结构鲜明的方向性特征相比有很大差异。关键词:桩基;水平荷载试验;变形;水平承载力中图分类号:TV72文献标识码:A文章编号:1673-8853(2022)12-0078-02ExperimentalStudyonHorizontalLoadofPileFoundationinaPumpingStationLIWeilin(ShenzhenWaterEngineeringTestingCO.LTD.,Shenzhen518000,China)Abstract:Takingthehydraulicengineeringpumpingstationasanexample,thehorizontalloadtestofpilefoundationinthesiteofpumpingstationconstructioniscarriedoutinthispaper.Thedeformationcharacteristicsofthepilebodyunderthehorizontalforcearestudiedandanalyzed.Theresultsshowthatitisveryreasonableandsafetosetthemaximumhorizontaldisplacementof6mminthesite.Inaddition,itismorescientificandreasonabletoselectthedisplacementcontrolandthehorizontalbearingcapacitycontrol.Themechanicalresponsesofpilesvariesgreatlyduetothedifferentpositionanddistancefromthefootoftheslope,showingthatthehorizontalbearingcapacityincreaseswiththedecreaseofthedistancefromthefootofslope.Whentheverticalcomponentforceactsontheslopesoil,thepilewillbesubjectedtorelativelyhighsphericalstress,whichimprovestheoverallresistanceabilitytoacertainextent.Thesoilslopehasthecharacteristicofuniformity,whichisquitedifferentfromtherockslopeinthedirectionalcharacteristicwhichtherockslopebodystructureisdistinct.Keywords:pilefoundation;horizontalloadtest;deformation;horizontalbearingcapacity■■■■■■■■■■■■■■作者简介:黎伟林(1983—),男,工程师...
