Abstract：Inrecent years，theconstruction technologyofurban 3Dmodels hasbeenapplied to the planning and research of numerous“digital cities”andkeyurbanareas，greatlyimproving thevisualizationanddatafieldcalculationcapabilitiesof resource surveyandmonitoringresults.Basedontheintegration technologyof multi-sourcedata，this articleproposesageneral framework fortheconstructionofanintegrated3Dmodelofabovegroundandundergroundareas.Keytechnologiessuchasdata storage，networktransmision，andspatialtopologyoptimizationarestudied，andanintegrated3Dmodelofabovegroudand undergroundareas inthesouthwesthirdringroadareaofBeijingisconstructedunifyandtransformmulti-source3Ddatathrough data standardization processng，anduseAI technologyand wavelet transform algorithms forintegratedstorage，management， andtransmisionThesurfacescene modeland3Dgeological modelarecombinedand preprocessedusing thebenchmark driling vectoras theverticalrulerofthestratumoptiizeandadjustthespatialtopologyerorsthatexistintheoverallandunitregions duringthe modelintegrationproces，solvetheconectionproblembetweespatialmodels，andimproveteaccuracyofteated integration.
