摘要
基于建筑信息模型(BIM)技术的桥梁信息化方法在桥梁施工及运营管养过程中应用越来越广泛。为解决在检测过程中由于病害位置、类型和信息表达不完善的弊端导致的病害分析不直观、无依据等问题,为桥梁检测技术提供新的分析思路,利用BIM技术,提出了一种可以实现病害级别分析方法,并针对一座连续刚构桥开展了建模过程。所建立模型考虑了结构本体模型和加固措施模型,可以进行裂缝和病害的自动化生成和属性信息附加,实现对裂缝走向、病害时间分布、裂缝纵桥向沿节段分布等内容的进一步分析,并输出图表以直观表达统计分析结果。提取关注部位的BIM模型数据导入ABAQUS中进行实体有限元分析,计算结果与初步分析结论吻合。同时,将计算结果以参数、表格映射和超链接等形式与BIM模型进行关联,实现多源数据的统一整合。
Bridge informatization methods based on BIM have been more and more widely used in the process of bridge construction and operation management.In order to solve the problems of unintuitive and unjustified disease analysis caused by the deficiency in disease location,type,and information data collected during the detection process,and to provide new innovative ideas for bridge detection technology,a rigid frame bridge was taken as an example,a method was proposed to achieve disease severity classification analysis and disease management based on BIM technology.A model considering the structural ontology model and the rehabilitation model was established,the automatic generation of cracks and disease information and the addition of attribute information could be realized,so as to achieve further analysis of crack direction,the time distribution of diseases,and the crack distribution along the longitudinal bridge segments direction,and output tables and charts to visually express the statistical analysis results.The BIM model data of the concerned part was extracted and imported into ABAQUS for solid finite element analysis.The calculation results were consistent with the preliminary analysis conclusions.At the same time,the calculated results were correlated with the BIM model in the form of parameters,table mapping,and hyperlinks to realize the integration of multi-source data.
