针对当前工业类基础（industry foundation classes, IFC）标准文件的开发应用存在文件格式转换繁杂、数据互操作性弱及信息有效利用率低等问题，提出一种IFC模型数据映射至数据库、建筑信息模型（building information modeling, BIM）在Web端重构及信息在线可视化分析的实施方法。基于Web框架，搭建IFC标准文件映射至关系型数据库的应用框架。该应用框架利用JavaScript语言对IFC标准文件深度解析，采用Python语言将IFC模型数据和建筑全生命周期有效信息储存至关系型数据库，结合实际案例及分析，展现并验证该应用框架的实施效果。结果表明：该方法可实现项目数据交互的完整性和高效性，支持建筑全生命周期相关应用的二次开发；同时融合智能建造技术和科学管理，提升BIM信息管理的有效性，促进建筑业数字化发展和智能化应用拓展。

Aiming at the problems of complex file format conversion, weak data interoperability and low effective information utilization rate in the development and application of industry foundation classes (IFC) standard documents, an implementation method of IFC model data mapping to database, reconstruction of building information model (BIM) on Web side and online visualization analysis of information was proposed. Based on Web framework, the application framework of IFC standard file to relational database was built. Using JavaScript language for deep parsing of IFC standard files, using Python language to store IFC model data and effective information throughout the entire lifecycle of buildings in a relational database. Combining practical cases and analysis, the implementation effect of this application framework was demonstrated and verified. The results show that this method can realize the integrity and high efficiency of project data interaction and support the secondary development of related applications in the whole life cycle of buildings. At the same time, intelligent construction technology and scientific management are integrated to improve the effectiveness of BIM information management and promote the digital development and intelligent application expansion of the construction industry.
