摘　　要：基于BIM技术在桥梁设计中应用,其首要问题就是选取一款能够满足桥梁骨架线平滑程度和局部构件精度的三维建模软件.因为CATIA软件自身拥有强大的曲线、曲面和空间结构设计能力,所以被越来越多的人用于桥梁设计阶段的三维建模.依据相应桥梁工程项目中特定要求选取法国达索公司的CATIA软件作为BIM技术的操作平台,以蝴蝶型拱桥的基本组成部分:基础、拱肋、桥面系、拉索以及支座构建桥梁三维模型的骨架,结合桥梁局部参数化的构件进行三维模型的建立.同时,根据三维模型的数字化、信息化和可模拟化等特点,对桥梁工程项目在其施工阶段进行分析与指导.从而提高桥梁设计师的工作效率和桥梁工程的质量.Based on the application of BIM technology in bridge design, the first problem is to select a software which can meet the precision of the bridge skeleton line and the local component. Because CATIA software has a strong curve, surface and space structure design capabilities, so more and more people use it to build three-dimensional modeling in bridge design. According to the corresponding specific requirements of bridge project, the CATIA software of Dassault from the France is selected as BIM technology operating platform. Based on the basic components of the butterfly arch bridge： the foundation, arch rib, bridge deck, cable and bearing, and the local parameterization component of bridge, the 3D modeling of the bridge is established. At the same time, according to the characteristics of digitalization, information and being simulated of the three-dimensional model, the construction stage of bridge engineering project is analysed and guided in order to improve the working efficiency of the bridge designers and the quality of the bridge project.
