Research on BIM Technology Modeling Method in Construction of Bridge Engineering

摘要

BIM technology covers a large number of information related to project which is serviced in the design of the construction project, construction installation, operation and the whole lifecycle by establishing the digital design of BIM model and plays a huge role in improving production efficiency, ensuring the quality of production, saving cost, shortening the construction period and other advantages. On the basis of a bridge engineering background, this paper introduces the characteristics and advantages of CATIA software, discusses the basic idea of the three-dimensional model of bridge engineering construction stage, analyzes the key and difficult problems in the process of modeling and puts forward the solution. Through the BIM three-dimensional modeling, the construction side of the project grasps more clearly particularly in the details of the situation. And the establishment of BIM model will directly meet the needs of construction management.
