摘要:赤水河大桥是千米级跨度的山区悬索桥，其规模大、技术难度高，传统手段难以满足设计要求。本项目通过将BIM技术引入到悬索桥设计中，解决了悬索桥线路比选、地形地质设计、锚碇设计、索夹设计及结构出图等设计过程中的困难。同时，也对项目进行BIM技术拓展应用，如二次开发、VR技术、构件编码等。实践表明，BIM技术在本项目中的应用，能够切实解决悬索桥设计过程中的一些难题，提高设计质量、节约成本，对同类型项目具有一定的借鉴意义。

Abstract: Chishui River Bridge is a suspension bridge in mountainous area with kilometer level span. Because of its large scale and complex technology, traditional design methods are not sufficient to meet the design requirements. BIM Technology is therefore introduced to the design of the suspension bridge in order to solve the difficulties in the design process of the suspension bridge including route comparison and selection, topographic and geological design, anchorage design, cable clamp design and structural drawing. Meanwhile, BIM Technology is also applied to the project, such as secondary development, VR technology, component coding, etc. It is proved that the application of BIM Technology in the project can effectively solve some problems in the design process of suspension bridge, improve design quality and save cost, which could be used as reference to similar projects.
