Abstract：：Inorder toreasonablyrealize thesafetyearlywarningclasificationofoperationalbridges，combinedwith the measureddataof denoising processing，the corresponding earlywarning criteria wereconstructedbased ontheaccumulated deformation sequence，rate sequence andacceleration sequence，torealize the multi-source information fusionof he safety earlywarningclasificationofoperational bridges，andfullyensure theaccuracyoftheclassificationresults.Theresultsshow thatPSO-DVMDmodelcanefctivelyremoverandom noisefrombridge deformationdataand issuitable fordenoising bridge deformationdata.Therearesomediffrencesintheearlywarning levelsofdiferentmonitoring pointsormonitoring itemsunder diferentcriteria，andthesafetyearlywarninglevelsofbridgesaredeterminedcomprehensivelyacordingtotheunfavorable principle.Theearly-waringclassficationofoperationalbridgesprovidesaquantitativeclassficationstandardforthesafety evaluation of operational bridges，which is worthy of further popularization and application.
