BIM-BasedTunnelInformationModellingFrameworkforDrill-and-BlastTunnellingProjects

Abstract

터널건설은건물및지상토목시설물프로젝트와기본적으로다르다.발파굴착은가장일반적이고융통성있는터널건설방법중하나이다.그러나,이방법은복잡하고어려운데왜냐하면흩어지고독립적이며다양한소스에서대량의데이터가생성되기때문이다.터널산업에서는여전히기존프로젝트관리기술을사용하여거의연결되지않은이러한데이터소스간의복잡한상호작용을관리하며모든관련측면을고려하지않고독립적인결정을내리는경우가많다.이러한맥락에서터널건설은예측하지못한상황,복잡한설계,비효율적인정보관리로인해불확실성과위험성을보여준다.건설산업에서빌딩정보모델링(BIM)은효과적인데이터정보모델링을통해이러한문제에대한해결책을제공한다.기존연구는매우일반적이고BIM의미론적모델을고려했으며전체발파굴착건설공정의일부에만집중했다.터널보링머신(TBM)프로젝트는BIM에서링크된데이터모델과다중모델개념을성공적으로적용했지만이러한기술은아직발파굴착터널에채택되지않았다.이러한격차를해결하기위해,발파굴착터널건설을위한5개의상호연결된데이터모델과프로젝트성능데이터를통합하여프로젝트관리,건설및제공을개선하기위한새로운BIM기반다중모델TIM(TunnelInformationModeling)프레임워크가제시된다.터널건설공정의데이터모델은IFC스키마구조의객체,관계및속성집합정의를기반으로IFC-터널클래스를제안하기위해연결된다.제안된프레임워크를검증하기위해수력터널프로젝트의구현사례연구가제시된다.이연구의결과는프레임워크가데이터공유,정보통합,데이터접근성,설계최적화,프로젝트커뮤니케이션,효율적인프로젝트관리,터널설계및건설공정의시각화를가능하게한다는것을나타낸다.|Tunnelconstructionfundamentallydiffersfrombuildingandabovegroundcivilinfrastructureprojects.Drill-and-blastisoneofthemostcommonandflexibletunnelconstructionmethods.However,itiscomplexandchallengingbecausethereisalargeamountofdataisgeneratedfromdispersed,independent,andheterogeneoussources.Thetunnelingindustrystillusestraditionalprojectmanagementtechniquestomanagecomplexinteractionsbetweenthesedatasourcesthatarehardlylinked,andindependentdecisionsareoftenmadewithoutconsideringalltherelevantaspects.Inthiscontext,tunnelconstructionexhibitsuncertaintiesandrisksduetounforeseencircumstances,intricatedesign,andineffectiveinformationmanagement.Buildinginformationmodelling(BIM)intheconstructionindustryprovidesasolutiontosuchissueswitheffectivedatainformationmodelling.ExistingresearchhasconsideredaverygeneralBIMsemanticmodelsandfocusedonlyasmallportionoftheentiredrill-and-blastconstructionprocess.Tunnelboringmachine(TBM)projectshavesuccessfullyappliedlinkeddatamodelsandmulti-modelconceptsinBIM,butthosetechnologieshaveyettobeadoptedindrill-and-blasttunnelling.Toaddressthatgap,anovelBIM-basedmulti-modelTunnelInformationModelling(TIM)frameworkispresentedheretoimproveprojectmanagement,construction,anddeliverybyintegratingfiveinterlinkeddatamodelsandprojectperformancedatafordrill-and-blasttunnelconstruction.DatamodelsoftunnelconstructionprocessesarelinkedtoproposetheIFC-Tunnelclassesbasedontheobjects,relationships,andpropertysetdefinitionsoftheIFCSchema.Tovalidatetheproposedframework,animplementationcasestudyofahydropowertunnellingprojectispresented.Theresultsindicatethattheframeworkfacilitatesdatasharing,informationintegration,dataaccessibility,designoptimization,projectcommunication,efficientprojectmanagement,andvisualizationoftunneldesignandconstructionprocesses.
