Abstract While many studies have investigated the application of BIM in helping the integration of architectural, construction or manufacturing projects, however, it has been barely used in road engineering due to the lack of pavement structure analysis in the present Road-BIM products. The aim of this research is to develop a framework for the integration of BIM and structure verification to improve the application of BIM in road engineering and thus reduce the mistake and repetition in pavement design. Relying on the capabilities of Dynamo, a three-dimensional road model with pavement controllable parameters was first established. Successful implementation of this step can facilitate the designer with more flexible and convenient needs in design process. Secondly, a subroutine is developed based on Python to combine Dynamo with the Mechanistic-Empirical Pavement Design Guide (MEPDG) which provides the pavement structure analysis. As a response to long-term development between BIM and road engineering, this paper contributes by offering innovative and practical solutions for integration of road design and pavement analysis, which effectively solves the long-existing defect that the pavement structure cannot be analyzed in the environment of BIM, and thus, will significantly promote the further application of BIM technology in the road industry.

基于BIM的三维道路设计与路面结构分析一体化

摘要 虽然许多研究探讨了BIM在帮助建筑、施工或制造项目的集成方面的应用，但由于目前的Road-BIM产品缺乏对路面结构的分析，它在道路工程中的应用很少。本研究的目的是开发一个将 BIM 与结构验证相结合的框架，以提高 BIM 在道路工程中的应用，从而减少路面设计中的错误和重复。依托Dynamo的能力，首次建立了路面可控参数的三维道路模型。这一步的成功实施，可以方便设计师在设计过程中有更灵活方便的需求。第二，基于 Python 开发的子程序将 Dynamo 与提供路面结构分析的机械经验路面设计指南 (MEPDG) 相结合。作为对BIM与道路工程长期发展的回应，本文为道路设计与路面分析的集成提供了创新和实用的解决方案，有效解决了长期存在的路面结构无法在环境中分析的缺陷。 BIM技术，将极大地推动BIM技术在道路行业的进一步应用。
