Application Research Of BIM Technology In Bridge Engineering Design And Construction Stage

In this paper,BIM technology is applied to the design and construction stage of bridge engineering,and the following problems are studied to provide reference for practical engineering projects:(1)According to the actual project and the specification requirements,select the design parameters of the bridge members,and carry out the secondary development through the Revit API,develop the modeling plug-in for the box girder,pier and bridge pile,and pass the cumbersome bridge component modeling work through the plug-in parameters.Automatic generation,and finally through the Revit visual programming plug-in,to achieve the rapid establishment of the full-bridge 3D model,providing a fast and efficient method for bridge 3D design.(2)By introducing Revit plug-in,the Revit model is directly imported into ANSYS finite element software to reduce the repetitive modeling work.Structural analysis such as static analysis,modal analysis and response spectrum analysis is carried out by ANSYS to ensure the safety and reliability of the design.(3)Through the BIM core software Navisworks,the construction simulation and construction management of the bridge are studied,and the mechanical properties of the construction scheme are verified by finite element to ensure the rationality of the construction scheme.(4)According to the research of finite element analysis results of bridges,this paper designs the layout of bridge health monitoring and monitoring sensors and construction monitoring sensors.
