BIM技术在大跨度斜拉桥设计中的应用

Application of BIM Technology in Long Span Cable-stayed Bridge Design

目的研究建筑信息模型(BIM)技术在大跨度斜拉桥设计中的应用方法,推广BIM技术在桥梁工程中的应用.方法利用BIM的核心建模软件Revit Structure建立斜拉桥各个构件族库,利用建立完成的族库逐步建立完整的斜拉桥的信息化模型,在族库的应用及斜拉桥模型建立和应用过程中探索出BIM技术在斜拉桥施工图设计中减少繁琐的工作量,减少错漏现象的发生中发挥的作用.结果桥梁工程族库能够很好地解决桥梁工程建模速度不高的问题;通过斜拉桥的信息化模型可以导出二维的施工图纸,同时可以生成三维的图纸,而且在任意视图下改变图纸的任意地方其他地方会自动修改.结论 BIM技术能够给大跨斜拉桥的设计带来极大的便利,节省大量的时间,减少由常规方法所带来的材料浪费现象,降低成本,具有在斜拉桥设计中推广应用的价值.

This paper is proposed to investigate the application of BIM（ building information modeling） technology in the design of long span cable-stayed bridge to extend the applied field of BIMtechnology. As the kernel modelling softw are of BIM,Revit Structure is used to build the family library of the constructional element of cable-stayed bridge. Then the complete model of cablestayed bridge is built using the family library. The designing process becomes more effective and simplified with less mistakes by using the family library and the model of long span cable-stayed bridge. The family library of bridge engineering manages to solve the problem of modeling speed as 2D and 3D construction draw ings of the cable-stayed bridge can be exported at the same time,and the draw ings will automatically updated with alterations. The BIMtechnology is recommendedfor designing long span cable-stayed bridge with the time-saving convenience and low-cost compared to the traditional design methods.
