Study On Construction And Application Of BIM Standard Model For Expressway Life Cycle

Based on the current concept of expressway construction management and its standardization development,this paper analyzes and analyzes the main ideas and technical characteristics of BIM technology,compares the application advantages of BIM in the whole life cycle of expressway,and clarifies the steps of expressway standard library construction expressway construction of different projects to determine the main standard components,and expressway engineering key sections and interchange junctions to build BIM analysis model,through the BIM standard library to build a strong way to promote the standardization of expressway construction,BIM technology in the expressway construction industry The further application of reference.According to the present situation of BIM technology application and the requirement of expressway life cycle construction management,this paper analyzes the advantages of BIM technology,determines the application point of BIM in all stages of life cycle,and establishes the standardized component library of expressway.The main research contents are as follows:(1)Combines the different specifications and standards at home and abroad on the definition of BIM technology,analysis of the BIM software application status,clear BIM technology,the main ideas and technical advantages.(2)This paper discusses the application status of BIM software in expressway construction,discusses the role of BIM technology in all stages of expressway construction,and comprehensively analyzes the application advantages of BIM in the whole life cycle.(3)This paper analyzes the role of BIM technology in the construction of the standard component library of expressway life cycle,establishes the steps of establishing the standardized component library,and establishes the corresponding standard library for the road,bridge and traffic engineering modules.(4)This paper mainly studies the method of establishing the standard component library of BIM analysis model such as expressway and interchange,taking the road specialty,the bridge professional and the traffic engineering specialty as the main works,and taking the actual project as an example.
