Abstract: In this paper, the author takes GanJiang Secondary Bridge project as an example to show how we use Dassault 3DEXPERIENCE software platform to establish the component template according to the bridge member type and how we form a complete model by automatically assemblying the component templates.And then, we simulates the design change and experience the convenience in this process.Furthermore, we simulates the whole process of bridge construction.In the end, the author hopes that this paper could help a lot to the application of BIM technology in similar bridge project.
