Abstract:Deformationmonitoringdatacanreflecttheservicebehaviorofultrahigharchdamsdirectly,
theycontainabundantspatiotemporalinformationandevolutionlaw,whichisofgreatsignificancetothe
longtermstabilityoftheproject.However,themultisourceandmultidimensionaldeformationmonito
ringdataareoftenaffectedbythemonitoringinstrumentitselfandotherexternalfactors,whichwillcause
interferencetothefollowingdataanalysis.Regardingtothemissingdataindamdeformationmonitoring
sequence ,thetargetmonitoringsiteswithstrongcorrelationwereobtainedbasedonthespatialcorrelation
ofmonitoringsitedeformationcalculatedbyAprioriassociationrule,andthenthedeformationmonitoring
datawereadoptedastheinputsamplestofillinthegapsindeformationmonitoringsequenceofthetarget
monitoringsitesusingBayesianoptimizedXGBoostregressionmodel.ThecasestudyofJinpingultrahigh
archdamshowsthatthismethodcanfillinthedeformationmonitoringgapsefficientlyandaccurately,so
itisapplicabletothefillingofmissingdeformationdataofsimilardamprojects.
