针对混凝土桥梁裂缝无法参数化表达的问题,本文将BIM技术引入桥梁管养检测裂缝病害的可视化中,以BIM核心建模软件Sketch Up为开发平台,IFC标准为基础通用语言,构建混凝土桥梁裂缝病害通用IFC参数模型。分析该裂缝IFC数据文件。提出基于IFC标准的立体模型病害参数化建模的新方法,对混凝土裂缝进行可视化表达。通过裂缝信息与模型的交互,实现裂缝病害的显示、病害特征信息属性导出、修改、导入和可视化的目标。
In order to solve the problem that the concrete bridges can not be parametrically expressed, this paper introduces the BIM technology into the visualization of the bridges and supports the crack detection. Based on the BIM core modeling software Sketch Up as the development platform and the IFC standard as the common language, Common IFC parameter model. Analyze the fracture IFC data file. A new method of parameterized modeling of three-dimensional model based on IFC standard was proposed to visualize the concrete cracks. Through the interaction of the crack information and the model, the display of the crack disease, the export, modification, import and visualization of the disease attribute information are realized.
