基于Bentley平台的铁路桥梁构件参数化建模研究 Abstract Withtheprogressofrailwayconstruction,theresearchofrailwaybridgecomponentsisalsobecomingmoreandmoreimportant.Inthispaper,wefocusedontheparameterizedmodelingofrailwaybridgecomponentsbasedontheBentleyplatform.Specifically,wediscussedtheadvantagesandchallengesofapplyingtheBentleyplatformtoconstructrailwaybridgecomponentsatalargerscale.Wealsopresentedthedevelopmentprocessandthekeyfeaturesoftheparameterizedmodelingtooldevelopedinthisstudyandthepreliminaryresultsofouranalysisandmodelingwork. Introduction Railwaybridgesarecriticalcomponentsofrailwayinfrastructure.Theyhavetomeetstrictstandardsregardingtheirstrength,durability,andsafety.Inrecentyears,severalresearchershavefocusedondevelopingadvancedmethodsfordesigningandanalyzingrailwaybridgecomponentswiththehelpofcomputer-aideddesign(CAD)systems.OnesuchsystemthathasgainedpopularityinrecentyearsistheBentleyplatform,whichoffersawiderangeoftoolsandfeaturesforCADmodelingandanalysis. TheBentleyplatformisapowerfulsoftwaresuitethatenablesuserstocreateandeditcomplexthree-dimensional(3D)modelsofinfrastructurecomponents,includingrailwaybridges.Italsoprovidesarangeoffeaturesforanalysis,visualization,anddocumentation.Theplatformisbuiltonamodulararchitecturethatallowsuserstocustomizeandexpanditsfeaturestosuitspecificrequirements.Giventhesefeatures,theBentleyplatformprovidesanidealenvironmentfordevelopingparameterizedmodelsofrailwaybridgecomponents.
