摘要:随着社会信息化的不断发展，BIM技术在建筑行业的应用日趋成熟，应用价值有目共睹。相比房建工程而言，基坑工程中BIM技术的应用深度显得较为薄弱，使用推广有一定的难度。本文将以国家会议中心二期基坑工程为例，从方案设计、模型建立、协调优化、施工模拟、工程算量等方面，探索BIM技术在基坑工程信息化中的应用。通过本项目上BIM技术的应用，总结岩土专业BIM技术应用的优势，为推广BIM技术在基坑工程中的应用奠定基础。

Abstract: With the continuous development of social informatization, the BIM technology is becoming increasingly mature in the construction industry, with its value obvious to all. Compared with that in the housing construction projects, the application of BIM technology in the foundation pit construction projects is relatively weaker in depth, and faces more difficulties in popularization. This paper takes the foundation pit construction project of the National Conference Center II as an example, to explore the BIM application in the informatized foundation pit engineering from different aspects of scheme design, model establishment, coordination and optimization, construction simulation, engineering calculation, and etc. Through overviewing the BIM application in this project, this paper summarizes the advantages of BIM application in the geotechnical specialty, which lays solid foundation for the popularizing the BIM application in the foundation pit projects.
