城市CORS系统在地面沉降监测中的应用
Title:TheApplicationofCORSSystemsinGroundSubsidenceMonitoring
Introduction:
Groundsubsidenceisaphenomenoncausedbyvariousfactorssuchasnaturalprocesses,geologicalcharacteristics,andhumanactivities.Themonitoringandmeasurementofgroundsubsidencearecrucialforurbandevelopment,infrastructuremaintenance,anddisasterprevention.Conventionally,groundsubsidencemonitoringhasreliedontechniquessuchasleveling,inclinometers,andgeodeticnetworks.However,thesetraditionalmethodshavelimitationsintermsofaccuracy,coverage,andefficiency.Inrecentyears,theuseofCORS(ContinuouslyOperatingReferenceStations)systemshasemergedasapromisingtechnologyforgroundsubsidencemonitoring.ThispaperexplorestheapplicationofCORSsystemsingroundsubsidencemonitoringanddiscussesitsadvantages,challenges,andfutureprospects.
