三维激光扫描在地铁盾构隧道变形监测的应用为题目，写不少于1200的论文 Abstract Subwayshavebecomeanindispensablepartofmodernurbantransportationsystems.Duringtheconstructionandoperationofsubwaytunnels,variousfactorsmaycausegrounddeformationandaffectthesafetyandstabilityofsubwaytunnels,whichposesasignificantthreattothesafetyofpersonnelandequipment.Therefore,real-timemonitoringofsubwaytunneldeformationisofgreatsignificance.Asahigh-precisionandnon-contactmeasurementmethod,3Dlaserscanningtechnologyhasemergedasapracticalapproachformonitoringthedeformationoftunnelstructures.Thispaperdiscussestheapplicationof3Dlaserscanningtechnologyinsubwaytunneldeformationmonitoring,includingtheprincipleof3Dlaserscanningtechnology,thedataprocessingmethod,anditsadvantagesovertraditionalmonitoringmethods,anddemonstratesitsuseinsubwaytunneldeformationmonitoringthroughapracticalcase. Introduction Asamasstransitsystemthatplaysasignificantroleinurbantransportation,subwayshavealwaysbeenaconcernofsociety.Manycitiesaroundtheworldhaveinvestedheavilyintheconstructionofsubwaystoalleviatetrafficcongestion,reduceenvironmentalpollution,andpromoteurbandevelopment.However,subwaysaretypicallybuiltthroughdenselypopulatedurbanareaswithcomplexgeologicalconditions,andpeopleandbuildingsarevulnerabletotheimpactofvibrationandsubsidencegeneratedbysubwayconstructionandoperation.Therefore,deformationmonitoringofsubwaytunnelsisacriticalelementinmaintainingthesafetyofthesubwayandensuringthecontinuedoperationofthesubwayinthefuture.
