基于可视化编程技术的道面裂缝信息模型动态管理方法研究

裂缝是机场道面最为常见的病害形式，掌握其发展规律对道面运维十分必要，然而以往裂缝病害大多以文字形式记录管理，其动态发展规律难以被掌握，管理人员也无法对其实时评价。为解决上述问题，基于BIM技术开发了一种道面裂缝信息单元，提出了道面裂缝病害信息模型快速建模方法，扩展了道面裂缝属性信息；通过可视化编程，实现了道面运维信息与病害模型的动态连接，结合PCI算法，实现了道面开裂病害实时评价；最后，引入时间参数，实现了物理裂缝发展与数字化模型的动态关联，并基于室内模型试验对所提方法进行了验证。研究表明，裂缝实体模型可实现对道面病害的集成化管理，依托可视化编程技术可实现道面裂缝动态信息集成与更新。研究成果可为全生命周期信息协同的机场道面运维与数字孪生技术发展提供基础。

Research on Dynamic Management Method of Pavement Crack Information Model Based on Visual Programming Technology

Cracks are the most common disease form of airport pavement, hence it is necessary to master its development law for pavement operation and maintenance. However, most crack diseases were recorded and managed in written form in the past, it is difficult to master its dynamic development law and evaluate its real-time performance. To solve the above problems, the paper develops a pavement crack information unit based on BIM technology and proposes a rapid modeling method of pavement crack disease information model, which extends the pavement crack attribute information. Through visual programming, the paper realizes the dynamic connection between pavement operation and maintenance information and disease model is realized, and the real-time evaluation of pavement cracking disease by combining PCI algorithm; Finally, the time parameter is introduced to realize the dynamic correlation between the physical crack development and the digital model, and the proposed method is verified based on the indoor model test. The paper notes that the crack solid model can realize the integrated management of pavement diseases, and the dynamic management of pavement cracks in the whole life cycle can be realized by relying on visual programming technology. The research results can provide a basis for the development of airport pavement operation and maintenance and digital twin technology with full life cycle information synergy.
