长沙香炉洲大桥在设计阶段的BIM技术应用实践

Application of BIM Technology in the Design Stage of Xiangluzhou Bridge in Changsha

作为工程领域的新兴技术和工具,BIM技术为桥梁工程设计提供了有效的信息化与三维化手段。在设计阶段,桥梁工程BIM技术应用主要涵盖方案汇报、参数化调整、工程量统计、设计复核、正向出图、有限元分析等应用。以长沙香炉洲大桥为依托,秉持客观务实的应用理念,伴随项目设计过程开展了造型设计、景观风貌评审、设计校核、工程量统计等一系列应用。前后迭代模型及输出成果达十余版次,形成了BIM模型报告、碰撞检测报告、设计校核报告等成果文件,对各BIM技术应用点进行了实践与剖析。通过项目实践,总结了一条注重实效的桥梁工程设计阶段BIM技术应用路线。

As a new technology in the engineering field,BIM provides an effective informational and three-dimensional tool for bridge design.In the design stage,the application of BIM Technology in bridge engineering mainly covers the application of scheme reporting,parametric adjustment,material statistics,design review,drawing output,finite element analysis and so on.Based on the Xiangluzhou Bridge in Changsha,this paper has carried out a series of realistic and rational applications,such as shape design,landscape review,design inspection,material statistics,etc.We have updated models and reproduced works for more than dozen editions,including BIM model reports,collision detections,design inspection reports and other multimedia outcomes.Complete practicing experiences of BIM application in bridge design have been summarized,especially effectiveness and feasibility are emphasized.
