基于Revit的地铁出入口快速生成方法及应用

Rapid Generation Method and Application of Subway Entrances and Exits Based on Revit

  • 摘要: 地铁车站出入口结构形式复杂多样,截面多变,传统Revit手动建模方式需反复剖切,放样与钢筋布置,效率低,易出错,制约BIM技术在地铁工程中的深化应用。针对这一现状,本研究以某地铁出入口的结构施工图为例,依托RevitAPI和C#编程语言进行二次开发,构建“参数驱动-规则匹配-实例生成”三步走算法,提出了一种基于Revit的地铁出入口快速生成方法。该方法以拾取的基准线以及窗体参数基于该算法,实现了:含支撑板或无支撑板的底顶板、侧墙、集水坑及顶板加腋等细部构造的实体模型自动生成;基于实体模型及参数实现异形板、斜板及集水坑板的纵筋、水平筋及梅花形拉结筋的自动布置及锚固处理;并拓展应用于地铁出入口的钢筋工程量统计得到钢筋总重为35750.88 kg,实现BIM数据传递;同时,设计自定义的地铁出入口Ribbon面板,通过按钮可实现自动生成,最后通过工程实例验证了算法可行性。该方法显著提升了Revit在地铁出入口工程的建模效率,为地铁工程BIM技术应用提供了新的技术路径,也为推动地铁工程领域正向设计的发展以及效率提升提供参考。

     

    Abstract: The structural forms of subway station entrances/exits are complex and diverse with variable cross-sections. Traditional manual Revit modeling requires repeated sectioning, lofting, and rebar arrangement, which is inefficient and prone to errors, constraining the deep application of BIM technology in subway engineering. To address this situation, this study takes the structural construction drawings of a subway entrance/exit as an example, relies on Revit API and C# programming language for secondary development, constructs a three-step algorithm of "parameter-driven, rule-matching, and instance-generation," and proposes a rapid generation method for subway entrances/exits based on Revit. Using the picked baseline and window parameters based on this algorithm, the method achieves: automatic generation of solid models for detailed structures including bottom/top slabs with or without support plates, side walls, sump pits, and haunched slabs; automatic arrangement and anchorage treatment of longitudinal bars, horizontal bars, and plum-blossom shaped tie bars for irregular slabs, inclined slabs, and sump pit slabs based on solid models and parameters; extension to rebar quantity surveying for subway entrances/exits with a total rebar weight of 35,750.88 kg, achieving BIM data transfer; and design of a custom Ribbon panel for subway entrances/exits enabling automatic generation through buttons. Finally, the feasibility of the algorithm was verified through engineering examples. This method significantly improves Revit modeling efficiency for subway entrance/exit projects, provides a new technical path for BIM technology application in subway engineering, and offers reference for promoting the development of forward design and efficiency improvement in the subway engineering field.
