摘　　要：BIM能够将桥梁工程项目通过三维数字技术模拟桥梁从设计到施工完整的真实信息,为工程设计和施工提供相互协调、内部一致的信息模型。相较于传统的二维平面图纸,BIM技术实现了资源一体化的设计施工,方便各专业协同工作,节约了工期和成本,使工程保质保量。成果模型均基于达索3DEXPERIENCE平台建立,按照铁路桥梁BIM设计项目统一建模标准命名。对于铁路BIM设计中数量较多,而形状相似的墩台结构,模型采用参数化驱动建模,通过改变参数,可迅速自动生成新项目的墩台模型,大大节省了新项目的建模时间,减少了出错概率。Through 3D digital technology based on BIM, information of bridge projects from design stage to construction stage can be simulated completely, which provides an integral model for engineering design and construction. Compared with traditional 2D engineering drawings, BIM technology achieved resource integration of engineering design and construction. It provides conveniences for different departments to corporate, also saves time and cost, which guarantee both quality and quantity for an engineering project. The outcome models were built based on the Dassault System 3DEXPERIENCE platform, and named according to the unified modeling standard of the Railway Bridge BIM Design Project. For a great number of piers and abutments with similar structure appearances in railway BIM design, by using parametric design method, it can generate new models which adapt to different projects automatically and quickly. It efficiently saves time and minimizes error probability for building new models.
