为系统研究BIM建模技术的发展情况,对建模过程中的关键环节进行总结,提出一种通用于矿山法隧道的BIM建模方法。首先,从平台选择、模型精度与轻量化、信息标准与分解标准、参数化建模4个关键环节对BIM建模方面的研究进行了分析;其次,基于以上研究分析,提出了一种基于Revit的适用于矿山法隧道全生命周期的BIM参数化建模方法,其可适用于隧道结构及地质模型的建立;最后,通过实际工程验证该方法的实用性。该方法通过EBS分解标准建立隧道构件模型库并通过WBS分解标准建立隧道BIM模型,其符合工程管理与项目管理的要求;而且,通过遵从IFC、IDM及IFD标准实现隧道BIM模型在不同平台之间的无损传输及数值软件的利用。

In order to systematically study the development of BIM modeling technology, the key links in the modeling process are summarized. A general BIM modeling method for mined tunnel is proposed. Firstly, the research on BIM modeling is analyzed from four key links: platform selection, model accuracy and lightweight, information standard and decomposition standard, parametric modeling. Secondly, based on the above research and analysis, a parametric BIM modeling method based on Revit is proposed for the whole life cycle of mined tunnel, which can be applied to the establishment of tunnel structure and geological model. Finally, the practicability of this method is verified by one mined tunnel real engineering. This method establishes the tunnel component model library through EBS decomposition standard and tunnel BIM model through WBS decomposition standard, which meets the requirements of engineering management and project management. Moreover, the non-destructive transmission of tunnel BIM model between different platforms and the use of other numerical software are realized by complying with IFC, IDM and IFD standards.
