In order to monitor the health status of the operation
tunnel in real time and improve the monitoring accuracy, the health system
structure of operation metro structure based on BIMbased
internet of things is studied by taking the monitoring project of Wangzong
Section of Wuhan Metro Line No. 3 for example. According to the characteristics
of monitoring indicators, such as settlement, inclination angle and
acceleration, the layout of sensor network and the transmission scheme of
monitoring date are described, and early warning analysis and evaluation result
system interface demonstration are conducted. Based on the content construction
of BIM core database and DYNAMO parameterization, a 3D modeling scheme for
operation tunnel is proposed. The integration of the 3D model and multigrade warning system are realized. The visualization of monitoring
and early warning is realized. The results can provide ideas for design,
transmission scheme selection, monitoring early warning analysis and
visualization of health monitoring system for operation metro structure.
