【摘要】 工程数字化BIM由于缺少核心技术的支持，其应用还处于初级阶段。论文在分析工程数字化BIM独有特点的基础上，凝练出工程数字化BIM关键技术，然后对国内在BIM关键技术方面的优势与不足进行分析研究，给出了国内突破关键技术的对策。研究结果表明，工程数字化BIM各个独特之处归结为一个关键的基础问题就是基于IFC数据交换标准的问题，它既关系到工程数字化BIM产品的全生命周期信息一体化，也关系到BIM应用的效益和可持续性。为突破国内BIM在关键技术方面的不足，应加强BIM标准体系的构建，大力发展BIM+现代信息技术，加快对国产BIM软件的研发工作。更多还原

【Abstract】 Due to the lack of core technology support, the application of engineering digital BIM is still in the initial stage. Based on the analysis of the unique characteristics of engineering digital BIM, this paper condenses the key technologies of engineering digital BIM, then analyzes and studies the advantages and disadvantages of domestic key technologies of BIM, and gives the countermeasures to break through the key technologies in China. The research results show that the uniqueness of engineering digital BIM can be attributed to a key basic problem, which is based on IFC data exchange standard. It is not only related to the information integration of the whole life cycle of engineering digital BIM products, but also related to the benefit and sustainability of BIM application. In order to break through the shortcomings of domestic BIM in key technologies, we should strengthen the construction of BIM standard system, vigorously develop BIM + modern information technology, and speed up the research and development of domestic BIM software.更多还原
