【摘要】：随着公路建设的大力发展,提高工程建设效率刻不容缓,特别是公路路线设计阶段的生产效率亟待提升。建筑信息模型(BIM)的提出,为实现建设项目全生命周期的信息交换、共享、集成与挖掘提供了有效途径。目前的公路BIM软件或平台缺少对路线设计过程中信息的深度支持。基于此,在分析公路BIM基本特征和要求基础上,基于Civil 3D软件,对路线设计过程中设计规则检查、评价信息实时反馈与扩展等问题进行研究。论文对BIM基本概念进行梳理,从逻辑结构、空间信息组织方式、公路设计过程、建设环境、多目标决策信息支持等五方面对公路BIM的概念进行分析和界定。以公路路线设计方法为研究对象,提出传统CAD应实现参数化建模、设计对象属性信息的拓展与集成评价信息等功能,以满足BIM在设计层面的要求,进而对公路路线BIM设计工具开发提出技术设想。基于AutoCAD Civil3D平台,根据公路路线BIM技术工具的需求分析,采用VB.NET语言二次开发了两种BIM对象模型。一是对Civil 3D设计规则检查类库进行拓展,将可量化的线形设计规范内建于信息模型中,在设计过程中可将规范冲突信息实时动态反馈,实现了设计规范自动检查,有助于设计者决策参考。二是对设计对象的非几何属性进行扩展,将运行速度属性拓展到图形对象中,建立了公路运行速度BIM模型,实现了运行速度的计算、实时查询及动态显示评价信息的功能,将评价融入到设计环节,有助于提高设计效率。论文初步研究了BIM应用于路线设计的理论和方法问题,构建了设计规则BIM模型与公路运行速度BIM模型,对设计过程中信息扩展和实时反馈问题进行了研究,并开发了相应工具。研究成果提高了对路线设计的支持层次与深度,为BIM技术在公路路线设计中的应用提供有效的技术手段。进一步研究中可考虑全生命周期下的功能拓展。
[Abstract]:With the development of highway construction, it is urgent to improve the efficiency of engineering construction, especially in the stage of highway route design. The construction information model (BIM) provides an effective way to realize the information exchange, sharing, integration and mining of the whole life cycle of the construction project. The current highway BIM software or platform lacks the depth support for the information in the course of route design. Based on the analysis of the basic characteristics and requirements of highway BIM, based on Civil 3D software, the design rules checking, real-time feedback and extension of evaluation information in the course of route design are studied. In this paper, the basic concepts of BIM are analyzed and defined from five aspects: logical structure, spatial information organization, highway design process, construction environment and multi-objective decision information support. Taking the highway route design method as the research object, the paper puts forward that the traditional CAD should realize the functions of parameterized modeling, the extension of the attribute information of the design object and the integration of the evaluation information, so as to meet the requirements of BIM in the design level. Furthermore, the paper puts forward a technical assumption for the development of BIM design tool for highway route. Based on AutoCAD Civil 3D platform, two kinds of BIM object models are developed by using VB.NET language according to the requirement analysis of highway route BIM technology tools. The first is to extend the class library of Civil 3D design rule checking, and build the quantifiable linear design specification into the information model. In the process of design, the specification conflict information can be dynamically feedback in real time, and the design specification can be automatically checked. It is helpful for designers to make decision reference. Secondly, the non-geometric attribute of the design object is extended, the running speed attribute is extended to the graphic object, and the BIM model of highway running speed is established, which realizes the function of calculating the running speed, querying in real time and displaying the evaluation information dynamically. It is helpful to improve the design efficiency by integrating the evaluation into the design link. In this paper, the theory and method of applying BIM to route design are studied, and the design rules BIM model and highway speed BIM model are constructed. The information expansion and real-time feedback in the design process are studied, and the corresponding tools are developed. The research results improve the level and depth of support for route design and provide an effective technical means for the application of BIM technology in highway route design. In the further study, we can consider the function expansion under the whole life cycle.
