摘　　要：在轨道交通项目建设过程中,对BIM技术的需求不断增加。文章结合既有轨道交通改造项目,通过应用BIM技术,对改造后的桥梁方案进行比选,将复杂的平面设计工作转化为三维设计,高效实现了更加直观的视觉效果,在项目前期既保证了既有线路正常运营,又将改造后的情况清楚呈现给参建各方,为设计、施工、运维协同奠定了坚实的基础。结果表明,采用Revit软件进行项目快速建模,可清晰展示改造后各种墩型的构造、钢筋布置及与梁部的整体协调性,有效弥补了传统设计方法的不足,为方案比选和设计阶段的沟通及后续施工阶段的质量控制提供了便利。In the process of rail transit project construction,the demand for BIM technology is increasing.Based on the existing rail transit reconstruction project,this paper compares and selects the bridge schemes after the reconstruction by applying BIM technology,transforms the complex plane design work into 3D design,and efficiently realizes a more intuitive visual effect,which not only ensures the normal operation of the existing lines in the early stage of the project,but also clearly presents the situation after the reconstruction to all parties involved in the construction,laying a solid foundation for the coordination of design,construction,operation and maintenance.The results show that the rapid modeling of the project by using Revit software can clearly show the structure of various pier types,the steel bar arrangement and its overall coordination with the beams after the reconstruction,which effectively makes up for the shortcomings of the traditional design methods,and provides convenience for the communication of the scheme comparison and selection and design stage and the quality control of the subsequent construction stage.
