摘　　要：针对目前BIM技术对桥梁建模的复杂繁琐和效率低下的问题,基于Auto CAD平台进行二次开发,利用Vlisp语言和Open DCL工具编制自动快速建模插件,研究钢箱梁BIM模型的参数化建模方法。该插件为界面友好的可视化工具,对桥梁建模时首先绘制二维构造图,以图中信息为基础进行面域拉伸和放样,从而快速构建出三维模型,为桥梁建模提供了三维可视化的新手段和理念。为了证明该方法能有效提升钢箱梁建模效率和准确度,以苏州中环北线二期工程为实例进行快速建模,实践表明,该方法所建模型能够快速准确的反应工程实例的相关参数,可推广到桥梁工程BIM建模中应用。Abastract: Aiming at the complexity and inefficiency of BIM technology in bridge modeling at present,based on AutoCAD platform for secondary development,using Vlisp and OpenDCL to develop an automatic rapid modeling plug-in and then the parametric modeling method of steel box girder BIM model is studied. The plug-in is a user-friendly visualization tool. When making a bridge modeling,it draws a two-dimensional structural diagram firstly,then based on the information of these diagrams three-dimensional modelings are built by extruding and lofting regions which provides a new means and concept of three-dimensional visualization for bridge modeling. In order to prove that this method can rapidly improve the efficiency and accuracy of bridge modeling,the secondphase project of Suzhou Central North Line is taken as an example for rapid modeling. Practices show that the method can reflect the relevant parameters of engineering examples quickly and accurately,and can be applied to BIM modeling of bridge engineering.
