基于BIM的钢箱梁自动建模研究

Research of Automatically Modeling of Steel Box Girder Based on BIM

钢桥的建设中,钢箱梁的设计是重要的组成部分。传统的2D图纸难以完全表现钢箱梁的复杂构造,利用BIM技术的特点与优势有效整合孤立的图纸信息。以上海北横通道新建工程北虹立交项目为依托,研究钢箱梁的基础建模流程。通过提炼基础建模流程,采用二次开发方式编制钢箱梁自动建模插件,有效提升钢箱梁建模效率与准确度。

The design of the steel box girder is an important part of the construction of steel bridge.Traditional 2D drawing couldn't express the complex structure of the steel box girder.The isolated drawing information could be integrated by using the advantage of BIM technology.This paper researches the basic modeling process relied on Beihong Interchange project of Shanghai Beiheng Channel new project.Through purifying the basic modeling process,the secondary development method is used to program the automatic modeling of steel box girder plugin,which can rapidly improve efficiency and accuracy of the modeling.
