Abstract: Aiming at the problems of safety and monitoring beyond the existing experience of metro station with arch cover method in Dalian area, this paper establishes a multi-information monitoring system for metro station with arch cover method based on BIM, which realizes the automatic monitoring of construction information.Firstly, on the basis of monitoring experience, this system proposes the installation plan of the automatic monitoring device of metro station with arch cover method, and arranges the sensors.Then, the main structure of the station and the BIM parametric modeling of the sensor are realized based on the Revit platform, and the monitoring properties of the sensor are expanded.Finally, through the design of BIM database, and in the form of secondary development, the construction information visualization monitoring system based on BIM is established, which realizes the connection between sensor model and monitoring data, and achieves the effect of information visualization query and discoloration warning.The system has been applied in Shikui Road Station of Dalian Metro Line 5 and achieved good results. The method in this paper provides advanced technical means for the information and visualization management of metro station with arch cover method.
