摘　　要：探讨BIM技术在广汕铁路跨京九铁路特大桥转体工程中的应用,并对桥梁转体的总体施工方案及关键步骤进行深入研究。通过实例分析,详细介绍转体施工的准备工作、监控设施布置及施工具体步骤,包括试转和正式转体的详细流程。在此基础上基于BIM技术,对球铰支座进行精细化建模研究,并进一步通过BIM技术优化了墩顶转体空间布局,预测并解决潜在问题。This paper discusses the application of BIM technology in the swivel project of Guangshan Railway across Beijing-Kowloon Railway Bridge,and makes an in-depth study on the overall construction scheme and key steps of bridge swivel.Through the example analysis,the preparation work,monitoring facilities layout and construction steps of the swivel construction are introduced in detail,including the detailed process of trial rotation and formal swivel.On this basis,based on BIM technology,the fine modeling of spherical hinge bearing is studied,and the spatial layout of pier top rotation is further optimized by BIM technology to predict and solve potential problems.
