摘要
随着建筑信息模型(BIM)技术的发展,其在桥梁建造中的应用不断深入,BIM几何与力学信息的融合技术能够解决制作与施工误差引起的构件不匹配问题。本文首先基于CATIA软件建立BIM模型,并从中提取力学信息,参数化处理后传递至ABAQUS软件中进行力学分析;然后,将力学分析数据信息传递回BIM模型中,实现BIM几何和力学信息的实时更新和可视化展示;最后,将现场实测数据与有限元分析数据进行对比分析。结果表明:BIM整体模型的传递和力学分析过程能够满足实际工程的应用需求,可以更有效地指导现场施工。
With the development of building information modeling(BIM)technology,its application in bridge construction has been gradually popularized.However,in the process of bridge construction,the model is not matched with the design stage due to the influence of many factors.In this paper,the BIM model was established based on CATIA software.After mechanical information was parameterized,it was transmitted to ABAQUS software for finite element mechanical analysis,and the mechanical analysis data was transmitted back to BIM model to realize real-time update and visual display of BIM geometric and mechanical information.Through the comparison between the field measured data and the finite element analysis data,it was found that the transfer and mechanical analysis process of the BIM overall model could meet the application requirements of practical engineering,and could effectively guide the field construction.
