With the rapid development of infrastructure construction, geotechnical engineering has always been worthy of attention due to its complexity and diversity. Accelerating the informatization of geotechnical engineering will contribute to the project management, but the information contained in geotechnical engineering cannot be well integrated because of the lack of unified data standards. Building Information Modeling (BIM) has been considered as an effective technology to manage information, and Industry Foundation Classes (IFC) in BIM serves as a neutral and open standard for the exchange of information. However, it was found that BIM cannot express the information of some structure objects and geological objects well during the construction process of geotechnical engineering. Combined with the characteristics of geotechnical engineering, taking advantage of the good extensibility of IFC, this paper proposes a “Built-In Generation Schema” for geotechnical structure models and a “Plug-In Extension Schema” for three-dimensional (3D) geological models, ultimately forming the basic data system of geotechnical engineering information models based on IFC. Applying extended IFC to the modeling process, the BIM-based modeling method of geotechnical models is proposed. In addition, an IFC-based platform is developed to integrate geological models and structure models for further displaying and analyzing of geotechnical engineering models. The work in this paper provides a feasible way and technical support for promoting the integration and sharing of geotechnical engineering information and enhancing the multiprofessional collaborative work.

基于IFC的岩土工程信息模型数据集成与共享开发

随着基础设施建设的飞速发展，岩土工程因其复杂性和多样性一直备受关注。加快岩土工程的信息化将有助于项目管理，但由于缺乏统一的数据标准，岩土工程中包含的信息无法很好地集成。建筑信息模型（BIM）被认为是管理信息的有效技术，而BIM中的行业基础类（IFC）是信息交换的中立和开放标准。然而，发现在岩土工程的施工过程中，BIM不能很好地表达某些结构对象和地质对象的信息。结合岩土工程的特点，利用IFC的良好可扩展性，本文为岩土结构模型提出了“内置生成方案”，为三维（3D）地质模型提出了“插入扩展方案”，最终形成了IFC的基本数据系统。基于国际金融公司的岩土工程信息模型。将扩展的IFC应用于建模过程，提出了基于BIM的岩土模型建模方法。此外，还开发了一个基于IFC的平台，以整合地质模型和结构模型，以进一步显示和分析岩土工程模型。本文的工作为促进岩土工程信息的集成与共享，加强多专业协作提供了可行的途径和技术支持。本文提出了一种岩土结构模型的“内置生成方案”和一种三维（3D）地质模型的“插件扩展方案”，最终形成了基于IFC的岩土工程信息模型的基本数据系统。将扩展的IFC应用于建模过程，提出了基于BIM的岩土模型建模方法。此外，还开发了一个基于IFC的平台，以整合地质模型和结构模型，以进一步显示和分析岩土工程模型。本文的工作为促进岩土工程信息的集成与共享，加强多专业协作提供了可行的途径和技术支持。本文提出了一种岩土结构模型的“内置生成方案”和一种三维（3D）地质模型的“插件扩展方案”，最终形成了基于IFC的岩土工程信息模型的基本数据系统。将扩展的IFC应用于建模过程，提出了基于BIM的岩土模型建模方法。此外，还开发了一个基于IFC的平台，以整合地质模型和结构模型，以进一步显示和分析岩土工程模型。本文的工作为促进岩土工程信息的集成与共享，加强多专业协作提供了可行的途径和技术支持。
