摘要:为了实现某大桥全生命周期的智能化建设和安全高效管理，基于建筑信息模型（BIM）技术建立了精细化的全桥三维模型，在BIM模型基础上进行了施工模拟、图纸审核、工程量统计、三维方案推演、装配式预制构件自动化流水线信息采集以及结合云技术的协同管理等BIM技术应用，实现了BIM自动化建模、钢筋自动化下料、BIM信息化平台、库化数据体系等研究领域的BIM技术升级。BIM技术在某跨海大桥项目建设中的应用，实现了桥梁工程项目的可视化和信息化管理，有效提高了施工的质量和效率，缩短了项目周期和成本，为该技术在跨海大桥工程中的应用积累了经验。

Abstract: In order to realize the intelligent construction and safe and efficient management of Yueqing Bay seacrossing Bridge, a refined three-dimensional model of the whole bridge is established based on BIM technology. On the basis of BIM model, the paper carries out BIM technology applications such as construction simulation, drawing review, engineering quantity statistics, three-digit scheme deduction, automatic assembly line information collection of prefabricated components and collaborative management combined with cloud technologyt. The BIM technology has been upgraded in such research fields as BIM automatic modeling, steel bar automatic blanking, BIM information platform and database data system. The application of BIM technology in the construction of a sea-crossing bridge project accomplishes the information and visual management of bridge engineering projects, which effectively improves the quality and efficiency of construction, shortens the project cycle and cost, and accumulates experience for the application of the technology in seacrossing bridge project.
