Mainlyforrailwaytunnelliningandlarge-scaleconcretestructures,fastandaccuratestrengthnon-destructivetestingisperformed.Theproductuseselasticwavesasamediumtodetecttheinternalstrengthofthestructure,andhasunparalleledadvantagesofultrasonicdetectorsandreboundmeters. First,thebasicprinciplesofelasticmodulusandstrength Theimpactelasticwaveisusedasthedetectionmedium.Thedynamicelasticmodulusofthematerialiscalculatedbydetectingthewavevelocityoftheelasticwave.Thecompressivestrengthoftheconcreteiscalculatedbasedonthecorrelationbetweenthedynamicelasticmodulusandthecompressivestrength.Thedynamicelasticmodulus. Thedynamicelasticmodulusofconcretenotonlyaffectsthedeformationofthestructure,butalsoanimportantindicatorofthequalityanddurabilityofconcrete: 1.Itcanreflecttherigidityofthematerialandisanimportantparameterinthecalculationofthedeformationofthestructure.Especiallyforhigh-strengthconcrete,themethodofsimplyusingcompressivestrengthtopushbacktheelasticmoldoftenhasalargeerror; 2.Theagingofconcretematerialsusuallystartswiththereductionofthespringmold,andthepoorconstructionofnewstructureswillalsoappearinthespringmold. Thedetectionofshotgunmodeismainlythroughthedetectionofwavespeed. Fora1-dimensionalhomogeneouselastomer,therelationshipbetweenthedynamicelasticmodulusEdandtheelasticwavePwavevelocityVp1canbeexpressedas: Amongthem,ρisthedensityofthematerial.Forconcrete,ρisgenerallyabout2400kg/m3.Whenthedetectionobjectistwo-dimensionalorthree-dimensional,thePwavevelocitychangestosomeextent. 2D: 3D: Forsurfacewaves(Rayleighwaves),therelationshipcanbeexpressedas: Rayleighwave: Ingeneral,thedynamicPoisson'sratioofconcreteis0.2to0.25.Thecomparisonbetweendifferentwavevelocitiesisasfollows: Accordingtothecalibrationdata,thecorrespondingrelationshipbetweenthedynamicelasticmodulusandthestrengthisestablished,andtheconcretestrengthvalueiscalculated. Two,simplecalibrationmethodofmodulustostrengthcurve Formoststructuralconcrete,itscompressivestrengthis20~60MPa.Inthisinterval,theinfluenceofdifferentshapedeterminationcoefficientsontheregressioncurveisnotlarge(asshowninthefigurebelow).Therefore,settingittoaconstant,suchas5.5,doesnotsignificantlyaffecttheaccuracyofthefittedcurve. Therefore,thereisonlyoneEAfortheparametersthatneedtoberegressed.Then,accordingtotheleastsquaremethod,itiseasytoperformregressionfittingonEA: Calibration-Establishingtherelationshipbetweenelasticmodulusandstrength Thestrengthtestrequiresthreesetsof150mm×150mm×150mmconcretestandardtestblockswiththesameproportions(especiallyaggregates)onthesite.First,testthedynamicelasticmodulusoftheconcreteofeachtestblock,andthenperformthecompressiontesttoobtainThestrengthofeachtestblockisusedforcalibration,thecorrespondencebetweentheelasticmodulusandthecompressivestrengthisestablished,theregressioncurveisfitted,andthecalculationformulaisderived.
