基于BIM技术的桥梁参数化建模方法

Application of Bridge Parametric Modeling Based on BIM

为了准确和高效地创建BIM(BuildingInformationModeling)桥梁模型,以效率最大化为目标,研究了一套基于AutodeskRevit建模软件的参数化模型创建方法,研究成果综合考虑了桥梁各个结构和附属设施等构件与Revit族样板如何匹配、模型属性添加方法、下一阶段模型应用等因素,形成了一套有针对性的构件创建及整合方法,最终作为BIM桥梁项目应用基础数据的重要一环.方法包含:模型构建划分、族样板选择、实体构件创建、实体构件参数化、应用类属性添加、构件整合拼装.

To accurately and efficiently create a BIM (Building Information Modeling) bridge model, this paper examined a set of parametric model creation methods based on Autodesk Revit modeling software. The research results comprehensively considered the various structures and ancillary facilities of the bridge. It included the factors such as how to match the Revit family template, the model attribute addition method, and next-stage model application form a set of targeted component creation and integration methods, and finally those factors became an important part of the BIM bridge project application basic data. The method includes: model construction division, family template selection, entity component creation, entity component parameterization, application class attribute addition, component integration assembly.
