BIM技术在网状吊杆拱桥设计阶段的应用

大半径平曲线网状吊杆拱桥空间关系复杂，仅通过二维图纸进行设计十分困难。在设计阶段利用BIM技术建立全阶段模型进行三维展示，，辅助设计确定吊杆定位、吊杆间距等重要数据，对多专业模型进行碰撞检查，实现了项目可视化、项目质量提升及数字化交付。展现BIM技术在桥梁设计阶段所发挥的作用及价值，可为同类型桥梁的BIM与设计深度融合提供借鉴。

Application of BIM Technology in Design Stage of Mesh Suspender Arch Bridge

In the design stage of long-radius horizontal-curve mesh suspender arch bridge, BIM technology is used to establish the full-stage model for 3D display, which is used to assist in determining the positioning of suspender, the spacing of suspender and the other important data. The collision inspection is carried out for the multi-specialty models to realize the project visualization, the project quality improvement and the digitization delivery. The effect and value of BIM technology in the design stage of bridge can provide the reference for the deep integration of BIM and design of the similar bridges.
