北京新机场超大平面航站楼结构工程BIM技术研究与应用

Research and Application of BIM Technology on the Super-Sized Plane Terminal Structural Engineering of Beijing New Airport

北京新机场航站楼及旅客换乘中心工程,位于北京市大兴区与河北省廊坊市之间,其核心区工程建筑面积约60万m2,建成后将与现有的首都机场、天津滨海机场和河北石家庄正定机场一起,形成京津冀机场群,加速京津冀交通一体化进程,是国家重点建设项目。该项目结合结构超大超长、中心区钢连桥跨度大、隔振系统节点复杂、钢结构支撑形式多样、屋面钢网架造型变化大和机电系统复杂,以及项目参与方众多,施工管理难度大等特点,在BIM技术的应用上,着重于将BIM技术与建造技术、信息化技术和项目管理相融合,科学高效地解决项目施工难题,提升管理效率,也使得本项目成为BIM技术向智慧建造方向发展的典型案例。

The Beijing new airport terminal and passenger transfer center project is located at Daxing District,Beijing,close to the city of Langfang in Hebei Province. The core area of construction project is over 600 thousand square meters. After completion,the Beijing new airport,together with existing Capital Airport in Beijing,Tianjin Binhai Airport and Shijiazhuang Zhengding airport,will form the Airport Group of Beijing-Tianjin-Hebei Area,to accelerate the Beijing-Tianjin-Hebei traffic integration. It is a national key construction project. The project faces many challenges including the oversized combined structure,large-span steel bridge,complex nodes of vibration isolation system,various forms of steel structure support,curved shape of roof steel grid and complex electro-mechanical system,as well as numerous project participants and difficult construction management. So,the application of BIM technology,focuses on the integration of BIM technology with construction technology,information technology and project management to find scientific and efficient solution to the project construction problems and to promote the management efficiency,which leads this project to a typical case of using BIM technology for smart building.
