【摘要】 水电工程信息模型是水电工程信息化管理的数据基础。本文通过引入建筑工程领域广泛应用的建筑信息模型(Building Information Modeling,BIM)以及相关国际数据描述交换标准——工业基础类(Industry Foundation Classes,IFC),根据水电工程的实际需求,在IFC标准体系的领域层、共享层、核心层、资源层中新增水电工程领域相关定义,实现了水电工程信息模型的基本数据描述。该模型采用实际工程数据进行了可行性和实用性验证,结果表明,相比原有IFC结构,本模型可以描述水电领域特有的构件和关系,提高了属性描述的精细度和规范程度,能够满足水电工程信息描述的专业需求,为水电工程全生命期数据存储与共享提供了技术支撑。更多还原

【Abstract】 Hydroelectric engineering information models provide a basis for data support to information management of hydroelectric projects. This paper discusses the Industry Foundation Classes(IFC) data model, a widely used data standard for building information models(BIM), and presents an IFC-based hydroelectric engineering information model. In this IFC-based model, definitions of the new entities characterizing hydroelectric projects were added to its layers of domain schema, shared schema, core schema and resource schema, and we tested it and examined its applicability to a real hydroelectric project. The results indicate that in comparison to the IFC standard, the new model enables a satisfactory description of the new entities and their relationships and improves accuracy and standardization in representation of project attributes. Thus it is a better data support to storage and exchange of the information for the full life-cycle of hydroelectric projects.更多还原
