Intelligent Construction Technology of Badaling Great Wall Station on Beijing-Zhangjiakou High-speed Railway

In order to realize the intelligent construction technology of deep buried super-large underground stations, the Badaling Great Wall Station on Beijing-Zhangjiakou High-speed Railway employs a series of explorations and research innovations from four aspects of tunnel survey, design, construction and monitoring. Firstly, the quantitative advance geological prediction technology based on the automatic sketching system of the tunnel face is developed, and the intelligent image prediction of the geological information of the tunnel face and the precise classification of the tunnel surrounding rock are realized. Secondly, the unified platform for multi-disciplinary collaboration is built with BIM technology to carry out the true three-dimensional integrated collaborative intelligent design. Thirdly, a real-time man-machine positioning management system is constructed to fulfill the efficient coordination and intelligent construction of passenger flow and logistics in complex underground stations. Finally, the tunnel structure safety intelligent monitoring system is used to monitor in real time the mechanical state of the surrounding rock and the supporting structure. The successful application of the tunnel intelligent construction technology in Badaling Great Wall Station has greatly improved the mechanization, informatization and intelligentization of tunnel construction, and promoted tunnel construction and comprehensive management.
