混凝土坝施工仿真过程中,为实现各专业的协同工作,会出现信息存储冗余及信息交互标准不统一等问题,从而影响模型的互操作性,降低了工作效率。为此,提出了基于建筑信息模型(BIM)与模型视图定义(MVD)的混凝土坝施工仿真模型,将信息交付手册(IDM)中的信息交互需求按IFC数据格式表达出来,以模块化的形式描述各个概念,确保了语义与逻辑的一致性,从而提高了模型信息的可读性。 In the process of concrete dam construction simulation, in order to realize the professional work of each specialty, there will be problems such as redundancy of information storage and non-uniform information exchange standard, which will affect the model interoperability and reduce the work efficiency. Therefore, a simulation model of concrete dam construction based on BIM and MVD is proposed, and the information exchange requirements in Information Delivery Manual (IDM) are expressed in IFC data format. In the form of modularization Describe concepts to ensure consistency between semantics and logic, thereby improving the readability of the model information.
