Application Of BIM Technology In Design And Construction Of Rigid Stiffening Suspension Continuous Steel Truss Bridge

As an important national infrastructure and a major artery of the national economy,highway transportation plays an important role in my country’s economic development.Since the reform and opening up,the country has increased investment in highway municipal construction,making the construction of highway bridges in China unprecedented gold In the future,the introduction of BIM(Building Information Modeling)makes it possible to build bridges with larger spans,more complex structures,and more beautiful appearance.The building information model is a new technology that is intelligent,digital,and informational in the construction and civil engineering industry.It can make the cooperation between construction parties become efficient,improve the efficiency of design and construction processes,and reduce In the past,some innocent waste in traditional construction has been achieved,so as to better control project cost and improve project quality.This article takes the Zengjiayan Jialingjiang Bridge in Chongqing as the research object,establishes the BIM model of the entire project,and completes the application of BIM technology in the design and construction of large-span rigid stiffened suspension cable continuous steel truss bridges.The design,engineering quantity statistics,main bridge construction simulation,visual cross-examination and other methods have saved a lot of engineering costs,and the project results have good practicability,reference and promotion value.The main content of the paper is as follows:1.Research the basic concepts and theories of BIM,explore the development of BIM technology at home and abroad in recent years;study the domestic and foreign BIM standards,summarize the domestic BIM standard composition system;compare the BIM software platform,The BIM software modeling platform suitable for this article was selected.2.Study on the refined modeling method of rigid stiffened suspension cable continuous steel truss bridge based on BIM technology,introduce the concept of steel truss bridge model accuracy,model classification and the meaning of model depth,complete the parameterization,modularization,PCL language and Revit+Dynamo plug-in four fast modeling methods.3.Explore the application of BIM technology in the design of rigid stiffened suspension continuous steel truss girder bridge,optimize the overall design of the bridge,complete the collision detection analysis based on BIM technology,trafficflow simulation analysis,main truss section Force analysis,anti-collision performance analysis of the main bridge.Explore the combination of BIM technology and other high-tech applications,and improve the scalability of BIM technology according to the "BIM+" approach.4.Explore the application of BIM technology in the construction of rigid stiffened suspension cable continuous steel truss girder bridges,explore the application of BIM technology in construction organization simulation,visual crossover,digital intelligent processing,etc;explore the progress,cost and quality of BIM technology,Security and other aspects of collaborative management;explore the interface between the BIM model and the finite element software Midas.Finally,the BIM foundation application of the Zengjiayan Jialingjiang Bridge in Chongqing during the design and construction phase was completed.
